GoBolt got its start as a storage solution for students living in residence, but co-founders Mark Ang and Heindrik Bernabe switched gears after deciding they wanted to have a positive impact on the planet

What started as a side hustle for ��ϲ�� graduate Mark Ang has since evolved into a multi-million-dollar third-party logistics company – one that aims to have a positive impact on the planet by using electric vehicles for package deliveries.

Ang’s startup GoBolt has raised more than US$160 million from investors to support expansion of its fulfillment, last-mile delivery and returns management services to major urban areas across Canada and the United States.

It’s also using the funding to increase the percentage of electric vehicles (EVs) it has on the road.

“I always tell the team, ‘We need to be fiercely competitive to win enough volume to have an environmental impact,’” says Ang, who earned his bachelor of commerce degree from ��ϲ�� in 2017 as a member of Trinity College.

GoBolt estimates that its approach currently prevents 20 tonnes of CO2 emissions each month, a number that increases as it adds more EVs to its fleet. The company also invests in tree planting and other restorative projects to sequester the emissions GoBolt does produce, with the goal of being carbon neutral by the end of 2023.

“What we do today is a great start, and it is a beacon for people, but it's not nearly enough to make a difference globally,” says Ang. “We're fiercely competitive in making this business a multi-billion-dollar global enterprise – and then we can start to effect real change.”

The story of GoBolt began when Ang was a ��ϲ�� undergraduate student in Rotman Commerce. He founded Second Closet, a storage service aimed at international students who needed to clear out their dorm rooms for the summer. Ang’s team rented trucks and scurried around campus to collect hundreds of boxes and random items. It was a lot of driving, a lot of parking tickets and a lot of stairs.

By offering a convenient service for a fraction of its competitors’ prices and an effective, flyer-based direct marketing campaign, the venture soon experienced rapid growth. Within two weeks, Second Closet was making $20,000 a month – pushing its resources to the limit.

“Every year got progressively crazier,” says Ang. “We had a dozen five-tonne trucks around ��ϲ�� every day in April and September. We would do thousands of pickups. It was just bananas.”

They needed help and they needed it fast.

Enter Michael Hyatt of the Creative Destruction Lab, a seed-stage accelerator that was founded at the Rotman School of Management.

The angel investor raised US$500,000 for Second Closet in a single day.

“In the realm of exceptional founders, Mark stands out as an evangelist who possesses the acumen to drive the business forward,” says Hyatt, entrepreneur and CDL founding partner who sits on GoBolt’s board of directors.

“Mark's intelligence and adeptness at building relationships were readily apparent. His ability to hustle and propel the business forward was instrumental in leveraging the connections within CDL.”

Hyatt also connected Ang with ��ϲ�� engineering student Heindrik Bernabe, who went on to become a GoBolt programmer, co-founder and CTO.

The business thrived but Ang and Bernabe still weren't satisfied.

“I didn't want our legacy to be that we help people hoard their stuff more efficiently,” says Ang.

Ang and Bernabe wanted to make a difference in the world, and so, with their fleet of trucks from Second Closet, they pivoted to logistics and shipping with GoBolt. At the time, using EVs commercially was a novel idea, but the newly formed GoBolt already had relationships with EV makers in Ontario and Quebec, as well as goods producers who cared about the fate of freight and addressing climate change.

“We wanted to be a 21st-century business for 21st-century brands, shoppers and merchants,” says Ang, whose clients include Endy mattresses and Frank And Oak apparel.

“We wanted to be change-makers in an antiquated industry.”

GoBolt’s made-in-Canada electric delivery vehicles can travel up to 400 kilometres on a single charge, depending on the payload and the EV battery’s natural enemy – freezing weather. But range is just a minor speed bump as technology improves and GoBolt adds service hubs and charging stations on its busiest routes.

“We're excited about what we're doing,” says Ang. “We don't feel super altruistic about it – we just know it's the right thing to do.”

Co-founded by Alex Cui last year, GPTZero has already raised US$3.5 million

With the ink barely dry on his master’s degree from the ��ϲ��, Alex Cui is tackling a towering issue spawned by the recent revolution in artificial intelligence tools like ChatGPT: How to tell if written content is generated by person or machine?

Enter Cui’s startup GPTZero. It analyzes patterns in writing, using sentence length and syntax to identify the likelihood text was generated by AI.

“GPTZero has a lot of imagination and potential in a future where AI is everywhere and it’s rampant,” says Cui, who studied computer science as a master’s student in the Faculty of Arts & Science and graduated in June.

"We haven't even really cracked the surface of what we could do.”

Cui co-founded GPTZero with Edward Tian last January – just a few weeks after ChatGPT went public and triggered a torrent of questions about academic integrity and authenticity – and has already drawn the attention of Silicon Valley investors, raising more than US$3.5-million to date.

As institutions around the world grapple with the impact of generative AI, ��ϲ�� has advised faculty to be clear with students about whether AI is permitted in their classrooms and actively discourages the use of all AI detectors, many of which are still in development, in favour of traditional methods of assessing students’ work.

Cui’s fascination with AI began at ��ϲ�� Schools – an independent secondary school affiliated with ��ϲ�� that Tian also attended before going to Princeton University – and at ��ϲ��’s Faculty of Applied Science & Engineering’s renowned DEEP Summer Academy. His early affiliation with the university gave him regular access to lectures by ��ϲ�� faculty, who, even a decade ago, urged Cui and his classmates to learn AI skills as soon as possible.

After high school, Cui earned his bachelor’s degree from the California Institute of Technology, but kept his Toronto connections. As an undergrad, he interned with one of the world’s leading experts on self-driving cars, ��ϲ��’s Raquel Urtasun, professor in the department of computer science and co-founder of the Vector Institute for Artificial Intelligence.

When Cui returned to ��ϲ��, Urtasun supervised his master’s thesis, which included writing code for the Waabi self-driving truck.

“��ϲ�� is one of the world leaders in machine learning,” says Cui. “There's no other ecosystem in the industry that combines AI innovation, commercialization and research partnerships.”

As GPTZero’s chief technology officer, Cui is overseeing fresh innovations, including plugins for Microsoft and Google products that help users detect AI text in any document or on any website.

Cui sees GPTZero offering immense value for several sectors, including publishing. He says the volume of author submissions is growing exponentially, especially with AI-driven content. Software like his could help editors determine what’s been written authentically, and how to take the writing to the next level.

Cui continues to be supported by ��ϲ�� and its partners. GPTZero recently started consulting with the Creative Destruction Lab at the Rotman School of Management and is also a member of the Vector Institute’s FastLane program, which advances AI adoption for Canadian startups and scaleups.

"Alex is an exceptional and experienced researcher and builder. His accomplishments speak for themselves. He is humble, knowledgeable and great to work with,” says Vector’s Junid Ebadi, the FastLane program’s business analyst.

"GPTZero is a fast-growing, well-resourced and driven company. They have been great partners for us, and we are happy to support them in their journey.”

Cui hopes his story will ease the stress of aspiring startup founders.

“It's not as scary as you think,” he says. “Especially in AI right now, a lot of people want to make bets on promising ideas, and I think if you are a talented individual solving a pressing issue, there's a good chance you can get some investors to fund your ideas.”

Despite the attention from media and investors, Cui is staying humble and focused on remaining a leader in AI detection.

“We have people who are betting on us, but I wouldn't say we're proven yet. To build a sustainable business, you can't just be a flash in the pan. We're still very much in the mindset that we are priming ourselves to go up against some stiff competition. We’re not going to take any liberties.”

Kelly Lepo is an education and outreach scientist at the Space Telescope Science Institute in Baltimore

Kelly Lepo likes to joke that she’s a real-life Lisa Simpson. Like the famous cartoon character known for her intellect and activism, the alumna of the ��ϲ��’s Faculty of Arts & Science is a self-proclaimed “nerd” who will share her love of science with anyone who will listen.

“I love blowing people’s minds,” says Lepo, who earned her PhD from the David A. Dunlap department of astronomy and astrophysics in 2015 and is now an education and outreach scientist at the Space Telescope Science Institute in Baltimore, Md.

Lepo supports the James Webb Space Telescope by communicating the observatory’s discoveries to the world. She works at the same institute that oversees the famous spacecraft’s systems, schedules telescope time for scientists and records data.

Lepo says ��ϲ�� was the perfect place to hone her public outreach skills as a TA and receive media exposure as a trusted expert in Canada’s largest astronomy department. She also learned how to educate large audiences and communicate complex theories about the universe.

“It’s an extraordinary experience learning from some of the top astronomers in a prestigious, yet nurturing environment,” says Lepo. “I remember the first time I landed in Toronto and it all sunk in that I was at one of the top universities in the world.”

During her PhD research, Lepo investigated stars that will explode as one type of supernovae to determine whether they were caused by two white dwarf stars colliding, or one star transferring its mass to another. She directed telescope operators in Chile and Australia to gather data from thousands of stars in the Small Megellanic Cloud, a tiny galaxy orbiting the Milky Way. In the end, she couldn’t find proof of supernovae caused by mass transfer, but her work was an important contribution to research in the field.

“In other studies, astronomers have used these supernovae to figure out the expansion history of the universe. They discovered our universe is not only expanding, but also accelerating in this expansion,” Lepo says. “Eventually, all galaxies are going to be so far away from each other that we're all going to be living in island universes.”

Her PhD adviser, Professor Marten van Kerkwijk, says Lepo was an efficient and driven astronomer.

“She has ample reason to be proud of her research,” says van Kerkwijk. “And I always appreciated the work she did while completing her PhD.”

In 2013, Lepo was a key organizer of the first ever West African International Summer School for Young Astronomers, a program partly sponsored by the Canadian Institute for Theoretical Astrophysics (CITA).

Lepo also cultivated her reputation as a trusted astronomy voice amid media coverage of the ancient Mayans' doomsday prophecy of 2012. Lepo debunked myths about killer solar flares and mysterious runaway planets on a collision course with Earth.

The experience complemented her TA duties in an Arts & Science class on the apocalypse, which took an interdisciplinary approach.

“We had someone from astronomy, someone from English and someone from sociology collaboratively teaching the course,” says Lepo. “That was really interesting to see how you could approach the same topic across several subjects.”

For her achievements inside and outside the classroom, Lepo won the Fieldus Award in 2014, given to one graduate student each year for excellence in leadership, teaching and research.

After graduation, Lepo taught physics at Gonzaga University before becoming the first co-ordinator of the McGill Space Institute at McGill University.

But she always ties her passion for public outreach back to ��ϲ��.

“One of my favourite memories is being in the middle of the St. George campus with a big inflatable sun and trying to get people to look at the sun safely through some solar telescopes; we must have come off as some kind of sun cult,” Lepo recalls.

“We explained to one person that the sun was much larger than the moon and they honestly had no idea, and this completely blew their mind. Those were the moments I really loved.”

Jamil Shariff, a PhD graduate in astrophysics, was inspired by science fiction to explore space and the future of humanity

Since watching Star Trek as a young boy in his parents’ living room, ��ϲ�� alumnus Jamil Shariff has dreamed of exploring strange new worlds – and boldly going where no one has gone before.

"Science fiction definitely sparked my interest in what the future of humanity would look like, the exploration of space and the development of amazing new technologies,” says Shariff, who earned his PhD in astrophysics in 2015.

Formerly a postdoctoral fellow at ��ϲ��'s Canadian Institute for Theoretical Astrophysics, Shariff is now engineering technology for one of the most ambitious projects in the history of crewed space exploration.

A senior leader in systems design at MDA (the Canadian company famous for building the robotic Canadarm on NASA’s space shuttle and Canadarm2 aboard the International Space Station), Shariff has been working on Canadarm3, the latest iteration of the iconic space hardware.

The new robotic arm is for Lunar Gateway, a space station planned for lunar orbit by the end of the 2020s. It will serve as a research outpost and cosmic pit stop for future missions to the surfaces of the moon, Mars and beyond.

MDA recruited Shariff several years ago, impressed by his PhD research under Professor Barth Netterfield at the David A. Dunlap department of astronomy and astrophysics in the Faculty of Arts & Science. Netterfield is one of the world’s foremost experts in developing systems for high-altitude balloon-borne telescopes.

“I wouldn't be where I am now if it weren't for professors like Netterfield,” Shariff says. “He’s a mentor, and it really matters to him if the people in his lab succeed.”

Part of an international team of researchers, Shariff and Netterfield designed, built, installed and operated two balloon-borne telescopes and analyzed their data. One of the projects, BLASTPol, examined the role played by magnetic fields in star formation. The other, Spider, was focused on understanding what happened in the very first moments after the Big Bang.

“The fact that I helped work on instrumentation that detected those microwave photons – which are like our baby picture of the universe, the oldest signal we can ever detect – that still amazes me,” Shariff says. “It's stayed with me all this time.”

During his PhD, Shariff spent several months working along other scientists at Antarctica’s McMurdo Station, maintaining and flying Spider in the skies over one of Earth’s most desolate locations. The experience – and learning how to explain his work to a wider audience – prepared Shariff for life after ��ϲ��.

“It's important to be able to tell your story – especially if you have a PhD in something like astrophysics – because a recruiter may not exactly understand what you do,” he says. “That really helped me.”

Nearly a decade after graduating, Shariff remains a champion of astrophysics research and ��ϲ��'s team of experts.

“You’ve got some of the best theorists in the world coming to us," Shariff says. “You have theory, observation and experimentation all happening at ��ϲ��. I think that should be a compelling case for donors who are passionate about furthering our understanding of the universe."

For ��ϲ�� alumna Sara-Jane Vigneault, museums can play a crucial role in the battle against misinformation

A teddy bear belonging to Holocaust survivor Marianne Constantine is one of the many donated objects ��ϲ�� alum Sara-Jane Vigneault has handled as a curator at the Montreal Holocaust Museum since earning her master’s degree in history through the Centre for European, Russian & Eurasian Studies (CERES) at the Munk School of Global Affairs & Public Policy and the collaborative graduate program in Jewish studies.

“What I appreciate most about this job is meeting survivors and families and working with them to tell their stories,” says Vigneault, who graduated in 2021. “I’ll never take this for granted, because it’s a privilege to be there for them.”

Vigneault notes that museums can play a crucial role in the battle against misinformation, whitewashing and conspiracy theories. A recent survey found that nearly a third of North American teens think the Holocaust is an exaggerated or fabricated event.

“We need to continue creating spaces to analyze the personal experiences of communities targeted during the Holocaust. I also believe it is necessary to offer dialogue with other genocides and conflicts,” Vigneault says.

These are important times of growth for Holocaust museums in Canada, with expansion of the Montreal Holocaust Museum and recent opening of the new Toronto Holocaust Museum, whose chief curator, Rachel Libman, is also an alum of ��ϲ��'s Faculty of Arts & Science and has collaborated closely with Vigneault.

Although not Jewish, Vigneault was particularly attentive to questions about the Holocaust and its legacies while pursuing her coursework in the faculty's Anne Tanenbaum Centre for Jewish Studies and CERES.

Her master’s project focused on Irène Némirovsky, author of Suite Française, and Némirovsky's daughters’ experiences of the war through their writings. Vigneault’s thesis, Filling and Bridging the Gaps: Two Daughters’ Paths to Retrieve, Uncover and Recollect their Mother from Beyond Obliteration considers Élisabeth Gille’s and Denise Epstein-Dauplé’s coping processes as they pieced together the memories of a mother that Vichy France seized from them.

Vigneault considers literature as a site of continuity between Némirovsky – who was arrested as a stateless Jew and killed in Auschwitz – and her daughters.

“I wanted to see how literature enabled them to reconnect and work through traumatic experiences,” says Vigneault, who contacted Némirovsky’s grandson as part of her research. She interviewed him and obtained permission to access crucial archives.

“Sara-Jane frames the narrative theoretically and analytically yet always keeps sight of Némirovsky and her daughters as people – individual women with personalities, feelings, fears and needs. It is not easy to write history in this way,” says Vigneault's thesis supervisor Doris Bergen, the Chancellor Rose and Ray Wolfe Professor of Holocaust Studies in ��ϲ��'s department of history.

Vigneault's research took her to Hungary's Living Memorial, where she explored the politics of memory and interviewed Holocaust survivors, scholars and activists (supplied image)

“She tackled enormous questions about the nature of historical research, the limits and possibilities of the archives and the responsibility of a scholar to the people – living and dead – who are our sources and our subjects.”

Experiential learning also bolstered Vigneault’s ��ϲ�� experience, including a research trip to Budapest, Hungary, where she worked on the politics of memory. There she interviewed scholars, survivors and activists about the Living Memorial, a counter-memorial created in response to the Hungarian government’s refusal to acknowledge the country’s role in the Holocaust.

Vigneault is currently pursuing her PhD in history at the University of Cambridge. She works on intimate contacts between French colonial soldiers and European women during the First and Second World Wars and investigates how French authorities tried to control racialized soldiers’ proximity to white women and maintain colonial borders.

For Vigneault, her work as a researcher and at the museum serves to bring forward the stories of marginalized groups and encourages people to reflect on their individual and collective roles and learn from history.

At the Montreal Holocaust Museum, Vigneault pursues that work alongside Jewish survivors like Marianne Constantine, who survived the Holocaust in Hungary with her mother and grandmother, only to be separated from them after the war. She reunited with her parents in Canada in 1952.

As a child, Constantine’s one constant was the teddy bear she kept throughout the ordeal – the same teddy bear she entrusted to Vigneault and the museum more than 75 years later.

Even while undertaking complex research, the human biology and immunology student took the time to help her peers

While studying for her honours bachelor of science degree, new ��ϲ�� graduate Irene Fang capitalized on opportunities both inside and outside the classroom.

Majoring in human biology and immunology in the Faculty of Arts & Science, Fang researched innovative methods in ultrasound detection driven by artificial intelligence (AI) and machine learning. She’s also working on research into cells and proteins in humans that could lead to new treatments and therapies for immunocompromised patients.

Even amid that busy schedule, Fang was determined to help others succeed. As a senior academic peer advisor with Trinity College, she was admired for her dedication to learning and the ��ϲ�� community.

“I want to keep giving back because I am so appreciative of the upper-year mentors I connected with, starting in first year,” Fang says. “They continue to serve as an inspiration, motivating me to further develop personal and professional skills.”

Fang spoke with Faculty of Arts & Science writer David Goldberg about what she learned during her undergraduate studies, the importance of peer support and her post-graduation plans.

Why was ��ϲ�� the right place for you to earn your undergraduate degree?

��ϲ�� provided a plethora of academic, research and experiential learning opportunities alongside a world-class faculty to help cultivate my curiosity and consolidate my knowledge. In conjunction with an unparalleled classroom experience, I gained a real-world perspective with international considerations through the Research Opportunities Program.

I would be remiss if I didn’t also mention how extracurricular activities enhanced and enriched my university experience. The many clubs at ��ϲ�� helped me focus on my passions and make meaningful connections with like-minded peers who became my support network, enabling me to reach my full potential.

How is your area of study going to improve the life of the average person?

It is absolutely fascinating that AI has already revolutionized the medical field. Specifically, AI possesses the potential to aid in the classification of ultrasound images, enhancing early detection and diagnosis of internal bleeding because of injuries or hemophilia. Overall, AI may lead to more efficient care for patients, thereby improving health outcomes.

In terms of my immunology research, since the memory B cells expressing the specific receptor are dysregulated in people suffering from some autoimmune disorders and infectious diseases, a better understanding of how memory B cells are regulated could provide valuable insight into the underlying mechanisms of such diseases so we can enable scientists to develop new therapies that alleviate patients’ symptoms.

What are you hoping to do after graduation?

I aspire to pursue a career in the medical field, conduct more research and nurture my profound enthusiasm for science while interacting with a diverse group of people. I hope to devote my career to improving human health outcomes while engaging in knowledge translation to make science more accessible to everyone.

Why was working as a peer advisor at ��ϲ�� important to you?

I remember feeling overwhelmed as a first-year student until I reached out to my academic peer advisors. Had I not chatted with them, I would not have known about – let alone applied for – my first research program. Looking back, it opened the door to many more new, incredible possibilities and opportunities.

This experience made me realize the significance and power of mentorship, inspiring me to become an academic peer advisor. Seeing my mentees thrive and achieve their goals has made this role so rewarding – so much so that I am determined to engage in mentorship throughout my career after graduation.

What advice do you have for current and incoming students to get the most out of their ��ϲ�� experience?

Ask all questions – because there are no silly questions. Get involved, whether it be volunteering, partaking in work-study programs, sports or joining a club. Meeting new people and talking to strangers can be daunting, but the undergraduate career is a journey of exploration, learning and growth.

Be open-minded and don’t be afraid to try something new. Immersing yourself in distinct fields enables you to discover your interests and passions, which can lead you to an unexpected but meaningful path.

Also, be kind to yourself because failures are a normal part of the learning process – what’s important is that you take it as an opportunity to learn, grow and bolster your resilience.

And finally, although academia and work can keep you busy, remember to allocate time for self-care. Exercise, sleep and pursue hobbies because mental health is integral for success in life.

Zhang decided to pursue graduate studies in computer science at ��ϲ�� after being inspired by AI pioneer Geoffrey Hinton

As issues around the usage and ethics of artificial intelligence (AI) continue to evolve, new ��ϲ�� graduate Guodong Zhang is ready to address those challenges.

“The public should embrace AI as a catalyst for positive change,” says Zhang, who graduates this month with his PhD from the department of computer science in the Faculty of Arts & Science.

“Ensuring that AI systems align with human values and remain under human control becomes increasingly critical. Addressing AI safety is one of the most important and impactful problems we face today.”

Zhang intends to be part of the solution. He applied to ��ϲ�� for his PhD several years ago, inspired by the “godfather of AI” Geoffrey Hinton, University Professor emeritus in the department.

As a PhD student, Zhang taught many courses at ��ϲ��. His study of theoretical foundations and practical algorithms for machine learning have already been adopted by major AI players, including Google Brain, DeepMind and OpenAI.

Ahead of convocation, Faculty of Arts & Science writer David Goldberg spoke with Zhang about his research and how ��ϲ�� prepared him for a future career in AI.

Why was ��ϲ�� the best place to earn your PhD?

I was captivated by the immense potential of deep learning, so ��ϲ�� was an obvious choice for me given its leadership in this area. Geoffrey Hinton and his students shocked the world with their results on ImageNet in 2012 with AlexNets, a neural network architecture which started a golden age for deep learning. Furthermore, the prospect of collaborating with the Vector Institute rendered ��ϲ�� even more special.

How do you explain your work with AI to people outside your field?

I focused on developing neural network models and algorithms that excel in fast training, robust generalization and accurate uncertainty estimation. With neural networks often comprising millions or billions of parameters, the challenge lies in understanding effective optimization techniques for these networks. I am also exploring the phenomenon of why neural networks have such impressive generalization abilities. And finally, another key aspect of my research was investigating whether neural networks can possess awareness of their knowledge gaps.

How is your work with AI going to improve life for the average person?

My research on neural network training dynamics holds significant importance in the realm of large language models and AI research. These models used in programs such as ChatGPT, which have become ubiquitous in our daily lives, play a vital role in various applications. For example, they assist us with translation, enhance our essay writing and serve as virtual assistants to address our queries.

There’s controversy surrounding some of the ways AI is being used – why do you think people need to embrace its potential?

The public should embrace AI as a catalyst for positive change because it enhances efficiency and productivity across industries, automates mundane tasks allowing for more meaningful work and improves problem-solving and decision-making through data analysis. In addition, it augments human capabilities and drives innovation while also helping us to address societal challenges like inequality and sustainability.

Embracing AI responsibly ensures transparency, accountability and ethical considerations, unlocking AI's potential for positive impact in our society. I think the public should also be involved in regulating AI, as AI systems could be very powerful and misuse of them could lead to catastrophic consequences.

What career path will you pursue after graduation – and how will your ��ϲ�� education help you excel?

I will work as an AI researcher in industry, focusing on large language models. My education at ��ϲ�� has equipped me with extensive knowledge in deep learning and artificial intelligence. Under the guidance of my advisor, Associate Professor Roger Grosse, and collaboration with colleagues, I have gained valuable insights into neural network training dynamics and AI safety.

This expertise enables me to enhance the efficiency of large language model training while ensuring alignment with human values. My PhD work on understanding neural network training with a noisy quadratic model has already been used by many big industrial labs (including Anthropic, DeepMind, OpenAI) in training the latest models.

What advice do you have for people considering their PhD – in your field or beyond?

I recommend everyone maintain a curious mindset and pursue their passions. Curiosity is vital for scientific progress. It is also crucial to remain open-minded and committed to lifelong learning. Our field is rapidly evolving, rendering knowledge from just a few years ago potentially outdated, so continuous learning is essential.

“The physical experience of watching the sun being totally covered is apparently life-changing,” says MacDonald, Dunlap’s outreach co-ordinator who earned her astrophysics PhD from ��ϲ��’s Faculty of Arts & Science in 2013.

“I’ve seen videos of people screaming with excitement when they see a total eclipse. I’m hoping to experience that level of joy this time around.”

If the skies are clear, MacDonald will fulfil that dream next spring during what could be the most viewed total solar eclipse in Canadian history. The path of totality soars over major urban centres, tiny towns and empty fields across Ontario – and it won’t happen again in the province until 2099.

The task force’s primary goal is education around safe viewing. It’s a major concern next spring because kids will be just getting out of school when the eclipse begins. In one solution, Dunlap teamed up with Discover the Universe and the Trottier Family Foundation to distribute thousands of eclipse viewers to classrooms across Canada.

“Astronomy outreach is one of Dunlap’s main pillars of purpose, and public education is embedded in the institute’s DNA,” says MacDonald, who as a student won a Fieldus Award for Excellence in Leadership and Research from the David A. Dunlap department of astronomy and astrophysics.

“Outreach has always been important to the Dunlap family and that’s a major reason why they’ve been such prolific donors and champions for ��ϲ��.”

Other considerations for the 2024 eclipse include community safety and travel. Thousands of people will flock to the best eclipse viewing areas that day, so don’t be surprised if there’s a traffic jam on Highway 401.

“I could try renting a boat,” says MacDonald. “Maybe I’ll just sail four kilometres south from the Toronto waterfront – that would be a nice view of everything.”

Growing up in rural Quebec, MacDonald was inspired by her father’s amateur stargazing. From the first time she gazed upon Saturn’s rings through the lens of his telescope, she knew the path she wanted to follow.

While earning her PhD, MacDonald studied ripples in spacetime triggered by two black holes about to crash into each other – otherwise known as gravitational waves. Her research was based on theories prior to the first detection of a gravitational wave in 2015.

She has a tattoo of that wave reading – like a wild cosmic heartbeat – proudly displayed on her right arm, paying tribute to the interstellar discovery.

MacDonald can’t say if next year’s eclipse will elicit a similar sentimental response.

“The sky gets very dark, and all the stars are revealed,” she says. “The birds go quiet because they think it’s nighttime. The temperature suddenly falls, and you can see the sun’s gases radiating from its horizons. Apparently, total eclipses are a whole other ballgame, and I can’t wait to see it.”

��ϲ�� alumnus Kokichi Kusano is preparing to debut his theatrical and musical work NAE, which translates to “The Rice Seedling,” at Toronto’s Harbourfront Centre – a performance years in the making and inspired by his studies in the Faculty of Arts & Science.

NAE runs from May 5–7 and uses elements of traditional Japanese theatre, music and art to tell a story of life on the island nation during a 13th-century famine.

“It's going to be quite a costume spectacle and a very ornate, unique experience,” says Kusano, who earned his honours bachelor of arts degree from ��ϲ�� as a member of Woodsworth College in 2005.

“I'm very excited to share that with Toronto.”

The story centres on a lonesome monk offering comfort to the dead as they float down a metaphorical river to the afterlife. The monk will soon discover the mysterious forces that hold the fate of humankind in the balance.

The monk’s character was inspired by a book Kusano read while studying in the department of East Asian studies: Hōjōki: A Hermit's Hut as Metaphor, by Kamo no Chōmei – one man’s chronicle of natural disasters and war in medieval Japan.

Many people and events in NAE are rooted in Kusano's studies and instructors at ��ϲ��.

“He was a great student,” says Ikuko Komuro-Lee, a linguistics expert and associate professor, teaching stream, in the department of East Asian studies. “He was very motivated, diligent and it was obvious he cared a lot about his Japanese heritage.”

Kusano earned a scholarship through the Dr. David Chu Program in Asia-Pacific Studies to study abroad at Kyushu University in Japan – on the same southern island his grandparents came from.

“I met a lot of musicians and artisans who were influential to my musical style and writing techniques,” he says. “��ϲ�� opened so many doors inside and outside the classroom.”

Kusano was born and raised in Toronto, but his grandparents came to Canada from Japan more than a century ago. However, those decades of distance couldn’t erode the connection to his ancestry – a nexus that grew even stronger when he started at ��ϲ�� in the late 1990s.

Kusano felt welcome right away, surrounded by students with similar life experiences who celebrated Asian cultures, languages and traditions in stark contrast to his childhood experiences.

"In the 1980s, being Japanese in Toronto was something that incited disgust in other people,” says Kusano. “The idea of eating sushi was cringe-worthy back then, but by the time I was in university, there were sushi restaurants all along Bloor Street.”

Canada recognized May as Asian Heritage Month more than two decades ago after ��ϲ�� alumna Vivienne Poy, who would later become a chancellor at the university, put forward a motion while serving in the Senate.

At ��ϲ��, Kusano noted a cultural shift. After a painful struggle, the Japanese community had found acceptance in Canada's largest city.

In first year, Kusano joined Toronto’s Nagata Shachu taiko drumming ensemble as a flutist. The group played many shows at Hart House and performed at Faculty of Music events, which prepared him for his post-university career as a professional composer.

Kokichi ramped up writing music and dialogue for NAE at the start of the pandemic, a time when he – and so many others – struggled with isolation and existential fears.

He was also dealing with his father’s terminal cancer battle. In the spring of 2020, Kusano’s family made the difficult decision to move his ailing father out of a locked down hospital, allowing him to spend his final days with loved ones.

“At the time, I had no control over outcomes or cancer treatments or symptoms, and some very key characters in the show are depictions of my father’s desperation as well as my own ups and downs,” says Kusano, explaining that NAE is about the struggle with uncontrollable forces.

"Several hundred years ago, people were at the mercy of nature because it was still very unknown and unconquered. Plays and stories from that time have a supernatural element; this belief that there are demons and ghosts around every corner and in every shadow.”

NAE marks the culmination of hard work, personal pain and virtual rehearsals with a cast across Canada that will be reunited just one week before showtime.

"We exercised great care as we took this from the original Japanese script and put it in English – all while we respected the shape of the traditions,” Kusano says. “We know our family, friends and the core Japanese community will come to support us, but we’re very excited to share this experience with a broader audience.”

Anjum Sultana credits her ��ϲ�� education for giving her the global perspective to make an impact as the inaugural director of youth leadership and policy advocacy at Plan International Canada.

An alumna of ��ϲ�� Scarborough and the Dalla Lana School of Public Health, Sultana advocates for the health of young women and children at development and humanitarian organization.

“We help young people to activate their global leadership by providing them with the skills, tools and networks to make meaningful change on children's rights. My team and I also do work influencing Canadian and global decision-makers on children's rights and equality for girls,” Sultana says.

“As a G7 nation, Canada can make a difference. Our world’s experiencing climate change, COVID-19 and conflict – what many are calling the ‘Triple C’. I want to figure out what positive role our country can play because we want to be that platform for global citizenship.”

During her undergraduate degree at ��ϲ�� Scarborough, Sultana took advantage of the university’s wide range of academic offerings after realizing that studying across disciplines could better position her to effect change by bringing new perspectives. She graduated with a double major in health studies and neuroscience, and a minor in psychology.

"Studying at ��ϲ�� gave me the tools to be a global citizen,” Sultana says. “We must understand how what happens in one part of the world impacts all of us.”

Sultana also completed a master’s of public health at the Dalla Lana School of Public Health with a focus in health promotion, global health and public health policy.

“I wanted to know how elements outside our bodies impact health and well-being,” says Sultana. “It was great to learn about the biology behind good health such as neurotransmitters, but it was also important to understand public policy and economics and how these variables influence health.”

While at ��ϲ��, Sultana volunteered with the ��ϲ�� International Health Program and War Child Canada, and was a first-year director with the Scarborough Campus Students’ Union, among many other activities. She received the Gordon Cressy Student Leadership Award in and the D.R. Campbell Merit Award.

“��ϲ�� instilled the importance of learning in the classroom,” says Sultana. “But it also inspired me to soak up everything I could through extracurriculars, which compounded my understanding of public service.”

Suzanne Sicchia, an associate professor, teaching stream, in ��ϲ�� Scarborough’s department of health and society, says she enjoyed sharing her classroom with Sultana.

“Her critical and creative contributions to our collective learning still stand out,” Sicchia says. “It has been wonderful to watch her career unfold. She’s doing important policy and advocacy work to the benefit of us all.”

Sultana makes time to give back to her alma mater. She has volunteered as a member of several mentorship programs at ��ϲ�� and offered her expertise as a guest speaker.

“I also work with the Public Good Initiative located on the St. George campus,” Sultana says. “It’s a pro bono consulting service for students who want to learn more about how they can support charities and non-profits. It's been such a joy to be part of that because I’m helping students think about how they want to contribute and play a role in those sectors, but also give back while they're at ��ϲ��.”

Growing up in Scarborough, Sultana remembers wanting to attend ��ϲ�� from a young age. Both her and her brother attended the university for their undergraduate and graduate degrees.

“I’m grateful my family achieved these milestones in higher education,” says Sultana, who was the first in her family to graduate from a university program in Canada. “And we were able to do it in our hometown.”
