It was a whirlwind week for the ��Ƶ’s ��Ƶ, who travelled to Sweden to officially accept the 2024 Nobel Prize in Physics alongside a jam-packed schedule of receptions, lectures, talks, ceremonies, banquets and media engagements.

The U of T University Professor emeritus of computer science known as the “godfather of AI” received the prestigious award during a formal ceremony at Stockholm Concert Hall — the main event during Nobel Week, held from Dec. 6 to 12 in Stockholm and Oslo.

He shared the honour with John J. Hopfield of Princeton University for foundational work that paved the way for today's rapid advances in artificial intelligence, which some have called “the next industrial revolution.”

From the days leading up to the ceremony to the celebrations overseas and back home in Toronto, here are a few highlights and behind-the-scenes glimpses of a historic moment for Hinton and the rest of the U of T community.

From better batteries to preventing memory loss, nearly four dozen projects at U of T and its partner hospitals are being supported by the Ontario Research Fund

Researchers in the ��Ƶ’s Thermal Management Systems (TMS) Laboratory are working to improve the way battery systems handle heat and develop structural battery pack components. 

“Whether they are being used for electric vehicles or for stationary energy storage systems that reduce strain on the grid, lithium-ion batteries are transforming the way we use electricity,” said Carlos Da Silva, senior research associate at the TMS Lab in the Faculty of Applied Science & Engineering and executive director of U of T’s Electrification Hub.

“Unfortunately, today’s batteries are still sensitive to temperature: if they get too cold or too hot, it can degrade their performance and even present safety risks. We are working on new technologies that make batteries more resilient to thermal fluctuations.”

The battery-related research is among nearly four dozen projects at U of T and its partner hospitals that are receiving almost $35 million in support through the Ontario Research Fund – Research Excellence (ORF-RE) and the Ontario Research Fund – Small Infrastructure (ORF-SIF). (See the full list of projects and their principal researchers below).

"Research at the ��Ƶ and at all universities and colleges across Ontario is the foundation of the province’s competitiveness now and in the future,” said Leah Cowen, U of T’s vice-president, research and innovation, and strategic initiatives.

“This investment protects and advances cutting-edge, made-in-Ontario research in important economic sectors and helps ensure universities can continue to train, attract and retain the world’s top talent."

At U of T Engineering’s TMS Lab, researchers led by Cristina Amon, a University Professor in the department of mechanical and industrial engineering, are working on two funded projects. They are developing advanced computational modelling and digital twin methodologies that predict and optimize how heat flows through battery packs. The methodologies are carefully calibrated and validated through industry-relevant experiments in the lab.

These methodologies will help battery designers anticipate and prevent thermal management challenges before they arise. It can also enable them to optimize the design and deployment of fire mitigation measures, such as ultra-thin heat barriers, within their battery systems.

The team is also collaborating with Ford Canada and several other companies in the energy storage space. For example, they have worked with Jule (powered by eCAMION) on the development of direct current electric vehicle fast chargers with integrated battery energy storage systems, one of which was recently unveiled on the U of T campus.

“We are grateful for this ORF-RE funding, which will accelerate our research and help us further expand our partnerships, ensuring that battery thermal innovations have a seamless transition from the lab to the marketplace,” Amon said.

“As a result of this work, the next generation of batteries will be safer and more resilient than ever before, which is especially important in colder climates like ours here in Ontario.”

“I think we all feel an enormous amount of pride in the fact that [U of T] is one of the places where modern machine learning was really born - in large part due to Geoff Hinton”

The ��Ƶ’s ��Ƶ officially accepted his Nobel Prize in Physics during a formal ceremony at Stockholm Concert Hall that included orchestra music, an opera singer and a stage lined with bouquets of flowers.

Wearing white tie and tails, Hinton strode across the dark blue stage emblazoned with the words “The Nobel Prize” to receive his Nobel medal and diploma from King Carl XVI Gustaf of Sweden. Then, as the Royal Stockholm Philharmonic Orchestra sounded a few triumphant notes, he bowed to the Swedish royal family, the audience and returned to his seat at the side of the stage.

And just like that, decades of scholarly endeavour in artificial intelligence (AI) – which began on the fringe of the AI research community and is now poised to forever change modern life – culminated in the U of T University Professor emeritus of computer science known as the “godfather of AI” receiving humanity’s most prestigious award for scientific achievement.

Hinton shared the 2024 Nobel Prize in Physics with John J. Hopfield of Princeton University, who made a similar journey inside the concert hall a few moments earlier. The pair were awarded the prize for discoveries and inventions that enabled machine learning with artificial neural networks, laying the groundwork for today’s AI boom.

“[��Ƶ] pioneered the efforts to establish deep and dense neural networks,” said Ellen Moons, the chair of the Nobel physics committee, during her introductory remarks. “Such networks are effective in sorting and interpreting large amounts of data and self-improve based on the accuracy of the result.

“Today, artificial neural networks are powerful tools in research fields spanning physics, chemistry and medicine, as well as in daily life.”

In fact, the three winners of the 2024 Nobel Prize in Chemistry – who were seated to Hinton’s left – drew heavily on AI for their work in predicting protein structures and computational design of proteins.

Back in Toronto, members of the U of T community gathered at watch parties on all three campuses to take in the livestream of the awards ceremony – a historic moment for the university.

On the St. George campus, more than one hundred gathered to watch and cheer in the main lobby of the Schwartz Reisman Innovation Campus – home to U of T’s Schwartz Reisman Institute for Technology and Society and the Vector Institute for Artificial Intelligence, where Hinton serves as an advisory board member and chief scientific adviser, respectively.

Among the gathered audience was Michael Guerzhoy, an assistant professor, teaching stream, of engineering science and mechanical and industrial engineering in the Faculty of Applied Science & Engineering who took Hinton’s course on neural networks and machine learning in 2005 – before going on to teach the same course himself several years later.

“I think we all feel an enormous amount of pride in the fact that this is one of the places where modern machine learning was really born, in large part due to Geoff Hinton,” Guerzhoy said. “I think a lot of us owe a personal debt of gratitude to him.”

Fourth-year undergraduate student James Wang said he was “in awe” as he watched Hinton receive his Nobel Prize.

“It makes you feel inspired. You want to be like him, you want to attain the highest level of achievement that anybody can achieve – and not just to do it for your sake, but also for the academic community at large,” Wang said.

There were similar expressions of pride and jubilation at U of T Mississauga, where community members congregated to watch the livestream in the atrium of the Communication Culture & Technology Building, and at U of T Scarborough, where a watch party was organized in the Meeting Place.

As per tradition, the awarding of the Nobel Prize medal and diploma took place on Dec. 10, the anniversary of the death of Alfred Nobel who, in his 1885 will, bequeathed his fortune to create the award.

The gold medal for the Nobel Prize in Physics depicts nature in the form of a goddess resembling Isis, her face covered by a veil held up by the Genius of Science. Inscribed are the Latin words, “Inventas vitam iuvat excoluisse per artes,”which are translated to: “It is beneficial to have improved (human) life through discovered arts.”

Later in the evening, Hinton joined his fellow Nobel laureates, their families, friends and dignitaries for a banquet at Stockholm City Hall.

In an interview with Swedish national broadcaster SVT on the sidelines of the event, Hinton said it was “very exciting but also very exhausting” to take part in the day’s Nobel events.

Reflecting on his upbringing and career, Hinton said his school years – raised as an atheist who went to a Christian school – helped prepare him for his early years as a cognitive scientist working in the then-peripheral area of artificial intelligence.

“From a young age, I was surrounded at school, everybody else had a different opinion and I thought they were wrong – that was very useful when I was studying neural nets,” Hinton said.

“For many, many years, there were only a few of us who believed in neural nets. Everybody else said this was a ridiculous thing to study. And it turned out we were right.”

The 2025 edition of the QS World University Rankings: Sustainability ranked U of T first out of more than 1,700 institutions across 95 countries

The ��Ƶ has been ranked the most sustainable university in the world for the second consecutive year.

The 2025 edition of the QS World University Rankings: Sustainability, released this week by London-based Quacquarelli Symonds, placed U of T first overall out of more than 1,700 institutions across 95 countries.

The closely watched ranking evaluates post-secondary institutions for their environmental impact, social impact and governance.

“On behalf of the ��Ƶ, I am thrilled that our university is once again ranked first in the world in the QS Sustainability Rankings,” said U of T President Meric Gertler. “The U of T community is profoundly committed to the advancement of sustainability as one of the most urgent challenges of our time.

“This year’s ranking confirms our resolve to help lead the way to a sustainable future.”

First launched in 2022, the ranking assesses universities based on QS World University Rankings data, including reputation surveys and research output related to the 17 UN Sustainable Development Goals. It also looks at institutional policies, operational data, alumni impact and national data from the Organisation for Economic Co-operation and Development (OECD) and World Bank.

To determine environmental impact, the ranking evaluates environmental education, research and sustainability. For social impact, it examines employability and outcomes, equality, health and well-being, impact of education and knowledge exchange. And for governance, the ranking looks at indicators such as student representation and transparent financial reporting.

U of T performed particularly well in the social impact category this year, moving up three spots to first globally. It also ranked fifth in the world for environmental impact and tied for 23^rd in governance.

U of T’s performance led a robust showing by Canadian universities. The University of British Columbia shared fifth spot with University College London, making Canada the only country to have two universities in the top five. Two other Canadian universities placed in the top 50: McGill University (15^th) and Western University (30^th).

The QS sustainability ranking comes as U of T forges ahead with a host of climate-focused initiatives on its own campuses including: Project Leap, a $138-million infrastructure project that will cut emissions on the St. George campus in half by 2027; Project SHIFT, a U of T Mississauga initiative to speed up the transition from natural gas to electricity; and a combination of new climate-responsible constructions and energy retrofits to older buildings at U of T Scarborough.

Spurred by these and other efforts, the university’s three campuses last year made a landmark commitment to reduce more greenhouse gases than they emit in the coming years. And U of T continues to make progress on its pledge to divest from fossil fuel investments in its endowment fund.

At the same time, U of T is working to enhance Canada’s green energy sector through projects like the Grid Modernization Centre, a state-of-the-art facility led by Climate Positive Energy, an institutional strategic initiative, that will serve as a hub for testing, development and commercialization.

U of T is also playing a leadership role in sustainability by engaging with regional, national and international partners. For example, the university acted as a founding member of the City of Toronto’s Green Will Initiative, collaborated with the Urban Climate Action Project to help implement the city’s TransformTO climate action strategy and contributed to the Toronto Region Board of Trade’s Banking on Green playbook, which helps Ontario organizations fund green retrofit projects.

Globally, U of T has convened networks aimed at mobilizing multi-sector partnerships, including the U7+ Alliance of World Universities, the University Climate Change Coalition (UC3) and the International Sustainable Campus Network (ISCN). U of T’s sustainability leaders have also been asked to share knowledge and experiences with other universities in Canada, the U.S., Mexico, Germany and other countries.

Most important, U of T is actively creating a new generation of sustainability leaders. Supported by the President’s Advisory Committee on the Environment, Climate Change, and Sustainability (CECCS), which recently created a new student leadership subcommittee, more than 2,000 undergraduate courses in 2024-25 now have a sustainability orientation.

Students also have the option of exploring sustainability from various lenses through the Sustainability Pathways program, or to contribute to projects on- and off-campus via the Campus as a Living Lab and Community-Engaged Learning programs.

Overall, U of T continues to be the highest-ranked Canadian university and one of the top-ranked public universities in the five most closely watched international rankings: Times Higher Education’s World University Rankings, QS World University Rankings, ShanghaiRanking Consultancy’s Academic Ranking of World Universities, U.S. News & World Report’s Best Global Universities and National Taiwan University World University Rankings.

In Stockholm for a series of Nobel Week events, the “godfather of AI” will officially accept his Nobel Prize in Physics at a ceremony on Dec. 10

The ��Ƶ’s ��Ƶ took to the stage at the Swedish Academy in Stockholm this weekend – two days before he officially accepts his Nobel Prize in Physics for fundamental work in AI – to deliver a lecture on the inventions and discoveries that led to him being given the prestigious award.

“Today, I’m going to do something very foolish – I’m going to try and describe a complicated technical idea for a general audience, without using any equations,” said Hinton, a U of T University Professor emeritus of computer science, prompting laughter from the audience.

The “godfather of AI” then proceeded to outline how decades of his fundamental research, and that of his co-laureate John J. Hopfield of Princeton University, enabled the development of artificial neural networks and machine learning – technologies that underpin today’s AI revolution.

The Nobel lectures are among the highlights of Nobel Week, which runs from Dec. 6-12 in Stockholm and Oslo and includes award ceremonies, banquets, media engagements and commemorations at the Nobel Museum. There is also a series of Nobel Week events taking place at U of T, including watch parties on all three campuses for the livestream of the Dec. 10 award ceremony.

Sunday’s first Nobel Prize lecture in physics was delivered by Hopfield, who shared how his fascination with the workings of the human brain inspired his development of the Hopfield network – an associative memory that can store and reconstruct patterns in data.

“How mind emerges from brain is, to me, the deepest question posed by our humanity,” Hopfield said.

When it was Hinton’s turn to take the stage, he described how he and Terry Sejnowski – one of Hopfield’s students – came upon a novel use of Hopfield nets: “Instead of using them to store memories, we could use them to construct interpretations of sensory input,” Hinton said.

He then went on to discuss the resulting Boltzmann machine, a type of neural network that is capable of recognizing elements within data.

Yet, despite its promise, the original Boltzmann machine was too slow, Hinton said, and it wasn’t until several years later that he came up with “restricted Boltzmann machines,” which impose limitations on connections between neurons in order to increase system efficiency – a development that would prove pivotal in training deep neural networks (Hinton donated an early Boltzmann chip, about the size of a postage stamp, to the Nobel Prize Museum).

Following the lecture, Hinton was joined on stage by Hopfield, with the pair sharing a vigorous handshake and posing for photos.

Separately, U of T convened an expert panel in Stockholm on Monday about the direction of AI research and development.

Moderated by Leah Cowen, U of T’s vice-president, research and innovation, and strategic initiatives, the panel included: Eyal de Lara, a professor and chair of the department of computer science in U of T’s Faculty of Arts & Science; David Lie, director of the Schwartz Reisman Institute for Technology and Society and a professor in the Edward S. Rogers Sr. department of electrical and computer engineering in the Faculty of Applied Science & Engineering; Tony Gaffney, president and CEO of the Vector Institute for Artificial Intelligence; and Amy Loutfi, professor of computer science and pro-vice-chancellor for AI at Örebro University in Sweden.

The conversation touched on areas including the promising applications of AI, how responsible deployment of AI can mitigate the technology’s potential pitfalls and implications of AI’s rise on education.

U of T President Meric Gertler said that the AI breakthroughs fostered by Hinton’s research were made possible by Canada’s longstanding support of basic research.

“Geoff was interested in the novel but unproven concept of artificial neural networks, an area that was sometimes described as the ‘unpromising backwater’ of AI research,” President Gertler said in his remarks introducing the panel, noting that Hinton joined U of T in 1987 and was one of the first scholars to receive support from the Canadian Institute for Advanced Research (CIFAR).

“Canada was investing in brilliant people, their ideas and their students – and those investments have paid off many years later.”

Canada was also the first country to launch a national AI roadmap, President Gertler said, in the form of the Pan-Canadian Artificial Intelligence Strategy – which funds three national AI institutes including the Vector Institute for Artificial Intelligence, which is now housed in U of T’s new Schwartz Reisman Innovation Campus. The state-of-the-art building also hosts the Schwartz Reisman Institute for Technology and Society, which is at the forefront of research and thought leadership on AI safety and responsible development, with Hinton one of its advisory board members.

“In short, Canada has played a key role in launching and driving the AI revolution and we’re a world leader in understanding and promoting safe, human-centred AI,” President Gertler said.

The theme of responsible AI was also brought up during a Q-and-A with Hinton, who revealed that the remarkable information-sharing abilities of large language models played a big role in sparking his now oft-repeated concerns around the current pace of the technology’s development.

“That’s when I came to realize that the fact that they’re so much better at sharing probably means that digital intelligence is just a better form of intelligence than us – and that’s what got me so worried,” he said.

Asked what responsible AI regulation looks like, Hinton said there must first be a consensus around solving the problem from a scientific standpoint – not unlike the scientific consensus that has emerged around climate change.

“Like the early days of climate change, the first thing to do is figure out what’s causing it and get scientific agreement on how you can fix it. Then, the second thing to do is get the politicians to do something about it … but here, we haven’t finished the first thing yet.”

��Ƶ, University Professor emeritus of computer science at the ��Ƶ and winner of the 2024 Nobel Prize in Physics, has added another prestigious award to his collection: the 2024 VinFuture Grand Prize.

The US$3-million prize, awarded by the not-for-profit VinFuture Foundation in Vietnam, recognizes seminal scientific advancements that are improving the quality of human life and forging a more equitable and sustainable world.

Hinton, known as the “godfather of AI,” shares the prize with Yoshua Bengio, Jen-Hsun (Jensen) Huang, Yann LeCun and Fei-Fei Li. The five are honoured for their contributions to the development and adoption of deep learning, which is revolutionizing fields ranging from biomedical research and transportation to manufacturing, clean energy and agriculture.

“The ��Ƶ couldn’t be more proud of University Professor Emeritus Geoff Hinton,” said Leah Cowen, U of T’s vice-president, research and innovation, and strategic initiatives. “When Geoff arrived at U of T nearly 40 years ago, his research into neural networks – influenced by his ideas about how the brain learns – was considered an AI backwater, if it was considered at all.

“Fast-forward to today, and his seminal work is transforming our world in ways that we’ve only begun to grasp. This award is a testament to the power of curiosity-driven research – and the impact of investing in brilliant, curious researchers.”

The VinFuture Foundation noted that Hinton and Bengio – a professor at the Université de Montréal – were awarded the prize for their research on neural networks and deep learning algorithms. LeCun, the chief AI scientist for Facebook AI Research who was one of Hinton’s post-doctoral students at U of T in the1980s, was recognized for helping develop convolutional neural networks for computer vision. Huang, the co-founder and CEO of NVIDIA, was recognized for his work on computational architectures for deep learning and accelerated computing, while Li, a professor at Stanford University, was celebrated for contributions to computer vision and large-scale image recognition.

In a video message, Hinton, an adviser at U of T’s Schwartz Reisman Institute for Technology and Society who is also co-founder and chief scientific adviser at the Vector Institute for Artificial Intelligence in Toronto, said he was honoured to share the award with such an esteemed group of researchers – including his fellow A.M Turing Award-winners Bengio and LeCun.

“The three of us spent our whole lives developing the technology of neural networks,” Hinton said in remarks that noted the collective nature of the achievement.

“I’m very happy to see that the VinFuture Prize recognizes the contributions of Jensen Huang in developing the kind of compute and software required for artificial intelligence, and Fei-Fei Li in providing the big data that was needed to prove that it worked.”

Now in its fourth year, the VinFuture Prize was created with the goal of celebrating scientific and technological innovations that are aligned with the United Nations’ 17 Sustainable Development Goals, which include poverty alleviation, renewable energy, ending hunger and improving health.

Friday’s award ceremony was attended by Vietnam’s Prime Minister Pham Minh Chinh and distinguished leaders, scientists and diplomats from around the world. It was broadcast live on Vietnamese television and streamed online.

“It’s terrific to see this recognition of Geoff’s extraordinary work and its potential to help address some of the world’s greatest challenges,” said Cowen. “Researchers around the globe – including a number of his former students – are using AI to help solve some of the most pressing challenges of our time in areas such as health care, sustainability and climate change.”

The prize comes as Hinton prepares to officially accept his Nobel Prize in Physics in Sweden on Dec. 10. He shared the Nobel with John J. Hopfield of Princeton University for foundational discoveries and inventions that enable machine learning with artificial neural networks.

Hinton, who joined U of T in 1987 after working in universities in the U.K. and U.S., has said that he plans to leverage his growing fame to spread awareness of the dangers of unchecked AI development – a warning he first shared after leaving a research position at Google in early 2023.
