As avian influenza spreads across species in new ways, a study with contributions from 91亚色 Associate Professor Iain Moyles suggests the mathematical models used to track it have not kept pace with reality.

For decades, bird flu, a virus that affects avian species鈥 respiratory and digestive systems, has been treated as a problem related to poultry farms and migratory birds, says Moyles. In recent years, however, it has spread beyond those boundaries, appearing in mammals, infecting dairy cattle and, in some cases, humans.

That shift requires better understanding of how the virus is evolving and circulating. 鈥淎vian influenza needs to be monitored carefully, as its ability to adapt and move between species raises concerns about its outbreak potential,鈥 says Moyles, who teaches in the Faculty of Science's Department of Mathematics and Statistics.

As with other infectious diseases, researchers rely on mathematical models to explore how bird flu might spread in situations that are difficult 鈥 or impossible 鈥 to observe directly, including rare spillover events where the virus jumps from one species to another.

These frameworks help decision-makers estimate how quickly a virus spreads, which species are most at risk and how effective control measures might be. Their accuracy can directly shape how outbreaks are monitored and managed. While bird flu is not currently transferring easily between people, its growing ability to infect a wider range of animals has raised concerns that it could increase risk for humans.

Moyles and his collaborators, however, noted that as bird flu was identified in new species, including dairy cattle in 2024, there had been little review on whether existing models capture emerging risks.

鈥淭his prompted us to perform a modern systematic review of mathematical modelling literature related to avian influenza to identify gaps,鈥 says Moyles about the work now published in .

The research team examined 30 peer鈥憆eviewed studies published between 2023 and mid鈥2025 on how bird flu spreads to assess whether current approaches reflect how the virus behaves today. The work was grounded in a 鈥淥ne Health鈥 perspective, which looks at connections between human, animal and environmental health.

What they found is most frameworks rely on a single, dominant approach. Nearly 90 per cent of the studies used compartmental models, which group populations into simple categories 鈥 for example, those who can catch the virus, those who are infected and those who have recovered. These models are relatively straightforward to work with and are often used to estimate whether an outbreak is likely to grow or fade.

The problem, researchers say, is many of these models are still based on earlier assumptions about how bird flu spreads, when infections were largely confined to wild birds and poultry. Since 2023, the virus has presented widely in birds, been detected in dozens of mammal species and, notably, has affected dairy cattle. Human infections remain rare, but are increasingly linked to contact with livestock. Despite this shift, most models overlook livestock almost entirely, limiting how well they capture bird flu transmission data and related emerging risks.

Studies using agent-based models, which simulate how individual animals or farms interact, and network models, which map how connections like trade or movement spread disease, was far less common. While these approaches can better capture real-world complexity, such as how poultry movements or farm networks influence transmission, they also require more detailed data and computing power.

The review also found broader gaps in how these models are built and tested. Many rely on assumptions or data from older studies, rather than being grounded in current outbreaks. Important features of the virus 鈥 such as how long it incubates, how immunity works or how it persists in the environment 鈥 are often simplified. Perhaps most striking, notes Moyles, is that very few models are tested against real-world data. Only two of the 30 studies compared predictions with actual outbreaks, raising questions about how reliable the methods for predicting virus behaviour is.

Models that leave out livestock, oversimplify immunity or fail to incorporate real evidence may give a false sense of certainty, especially when used to guide policy in fast鈥憁oving outbreaks where the virus behaves differently than in the past.

鈥淎 lack of understanding of the multi-host transmission and spillover of avian influenza creates gaps in surveillance capabilities,鈥 says Moyles.

To address this, the researchers recommend a shift toward more biologically grounded and data-driven modelling by accounting for livestock, incorporating data on how immunity works, including antibody responses and testing model predictions against real-world outbreaks. They also suggest using multiple approaches together, rather than relying on a single forecast, and call for better surveillance data and greater transparency in how models are built and reported.

鈥淲e hope that this review will motivate more One Health mathematical modelling studies and the collection and use of data that support them. This will improve the ability to design meaningful intervention strategies,鈥 says Moyles. 鈥淚n the long term, the goal is to develop models that better capture spillover risk, including early warning signs of the virus emerging in new species and its potential to cause outbreaks.鈥

Carswell Observatory to track and record the Orion spacecraft during the historic mission around the moon.

The post 91亚色 U students track NASA鈥檚 Artemis II mission appeared first on YFile.

Students at 91亚色 captured early-morning images of NASA鈥檚 Artemis II Orion capsule from the Allan I. Carswell Observatory (AICO), contributing tracking data and a moving image as the spacecraft carried Canada鈥檚 first astronaut to fly around the moon.

From 3 to 4 a.m. on April 8, physics and astronomy students used the observatory鈥檚 one-metre telescope to image Orion as it travelled back toward Earth after looping around the moon. The capsule carried Canadian astronaut Jeremy Hansen.

The observation was led by graduate student Sunna Withers and supported by Nakul Sethuram Ramjee, an undergraduate student. Ramjee also completed the data reduction, animating the images to produce a short movie showing the spacecraft moving against background stars.

A screenshot of the Orion spacecraft imaging captured by 91亚色 students.

"I worked on processing the Artemis II data using Siril (an astronomical image processing software)," says Ramjee. "I uploaded the sequence of images and applied auto stretch to enhance the brightness and contrast, and then converted the sequence into a video to visually capture it's movement over time."

Because Orion appeared low on the horizon, the imaging capture pushed the limits of the telescope. The team used a Mallincam camera mounted on the one-metre telescope at 91亚色鈥檚 Keele Campus to capture the historic mission.

Elaina Hyde, director of AICO and associate professor in the Faculty of Science, says this kind of telescope access and training is rarely available to undergraduate students. Having the largest telescope on any Canadian post-secondary campus, she notes, "is quite a boon to any space fan at 91亚色."

She adds that certification to use the telescope is open to all undergraduate students.

Withers describes the event as "very exciting." Because the capsule was barely visible against the stars, it took careful comparison of multiple images to identify its motion. "It was a great feeling once I spotted it," says Withers. "Artemis II is a historic mission, especially with a Canadian on board, and its amazing that we were able to get a glimpse of it through the one-metre telescope."

A video of the spacecraft imaging, along with a technical discussion of the observations, is available for public viewing on .

鈥淭his work highlights how 91亚色 students participate directly in space-related observation, data analysis and telescope operations using on-campus infrastructure,鈥 says Hyde. 鈥淢onitoring mission activity gives students experience with real-time space missions.鈥

Alongside astronomical research, the observatory tracks satellites and space missions connected to human exploration programs.

Artemis II is part of NASA鈥檚 broader Artemis program that is preparing for a return of astronauts to the moon in 2028.

AICO supports both research and public engagement and offers free weekly public tours on Wednesday evenings, featuring its 60-centimetre and one-metre telescopes. This summer will also host the 2026 AstroFair 鈥 a community fundraiser to support AICO鈥檚 programming. More details will be released ahead of the Aug. 29 event.

Can AI reduce bias in liver transplant waitlists? /yfile/2026/04/17/can-ai-reduce-bias-in-liver-transplant-waitlists/ Fri, 17 Apr 2026 15:12:23 +0000 /yfile/?p=405908 A 91亚色 researcher is helping to define how emerging technologies can be used to support more equitable health care decisions.

The post Can AI reduce bias in liver transplant waitlists? appeared first on YFile.

A new international study involving 91亚色 researcher expertise shows that AI could help make liver transplant decisions more consistent, transparent and evidence-based, especially when resources are limited.

The study, published in , tested a multi-agent system built with large language models (LLMs) to simulate the work of a liver transplant selection committee 鈥 a multidisciplinary group that decides which patients are placed on transplant waitlists.

Using real-world transplant registry data, the AI system demonstrated high accuracy in identifying patients who are likely to benefit from a liver transplant and those for whom transplantation would be unlikely to help.

鈥淟iver transplantation is a rare case in medicine where access to a life-saving treatment is limited by organ availability,鈥 explains co-senior author Divya Sharma, assistant professor in the Faculty of Science. 鈥淒ecisions about who is waitlisted are complex, and committee deliberations can be subject to unconscious bias聽where a clinician's own background or identity may subtly influence their judgement,聽even when national guidelines are in place.鈥

Researchers set out to test whether AI agents 鈥 each assigned a clinical role 鈥 could support more objective decision-making. To test the approach at scale, researchers evaluated the system against transplant outcomes data.

The study analyzed 20 years of data from more than 8,000 adult liver transplant recipients in the U.S. using the Scientific Registry of Transplant Recipients. A simulated group of patients with known contraindications was also created to test the system鈥檚 accuracy in flagging cases that should be excluded from transplant consideration.

Results show the AI committee predicted one-year post-transplant survival with 92 per cent accuracy and six-month survival with 95 per cent accuracy. Contraindications were identified with an accuracy of more than 98 per cent, thereby identifying transplant candidates efficiently.

The research team also examined where errors occurred to better understand where the AI system works well, and where it needs careful oversight and improvement. The authors caution that continued monitoring is needed because transplant data can reflect broader inequities in access to health care.

鈥淥ur work positions LLM-based multi-agent AI systems as potential clinical decision-support tools, rather than replacements for human judgement,鈥 says Sharma. 鈥淲hile AI shows promise in making liver transplant decisions more objective, it鈥檚 crucial to emphasize that the final responsibility must always remain with transplant teams and human oversight is critical to address ethical considerations.鈥

Sharma says while more research is needed to test the AI tools in real-world settings across different health systems, AI-supported committees have potential to help standardize complex medical decisions where resources are limited.

Allan Carswell, a visionary scientist, educator, entrepreneur and philanthropist whose life and work profoundly shaped Canadian science and public life, passed away on March 29 at the age of 93.

At 91亚色, his impact was immeasurable and will continue to enrich the lives of students and scholars for generations to come. His legacy at the University spans his influential research in physics, decades of teaching and leadership, and transformative philanthropy that strengthened scholarship across disciplines.

Allan Carswell
Allan Carswell

鈥淒r. Carswell鈥檚 passing marks the loss of a pioneering force in physics, a devoted builder of institutions and a generous supporter of education, health care and the arts,鈥 says Interim President and Vice-Chancellor Lisa Philipps. 鈥淗is prolific career reflected a rare combination of scientific excellence, entrepreneurial vision and profound commitment to the public good, leaving an indelible mark on Canadian science, higher education and community life.鈥

Carswell earned his BASc in engineering physics (鈥56), MA (鈥57) and PhD in physics (鈥59) from the University of Toronto, which he followed with a postdoctoral research position at the Institute of Theoretical Physics at the University of Amsterdam. It was there that he focused his career on high-power lasers and the emerging field of laser radar, now known as LiDAR (light detection and ranging).

Nearly 58 years ago, Carswell joined 91亚色 as a professor of physics. During his tenure, he pioneered LiDAR applications for remote sensing, environmental diagnostics, and atmospheric monitoring (including Arctic ozone layer observation). He was internationally recognized as a founding figure in LiDAR technology, and his research innovations revolutionized Earth and planetary mapping, atmospheric science and space-based environmental monitoring.

Most notably, LiDAR technology developed through his research was later deployed by NASA as part of the Mars Phoenix Lander鈥檚 weather station, a mission led by 91亚色 scientists and work that led to the first observation of falling snow on Mars.

His career at the University spanned three decades. He was named professor emeritus in 1998.

In 1974, Carswell founded Optech with his late wife, Helen Carswell, who played a formative role in the company鈥檚 growth. Initially operating the business out of their family home, the company bridged the gap between academic research and real-world, deployable technologies. Under Carswell鈥檚 leadership as founder and president (1974-2000), Optech evolved into a global leader in high-tech laser systems. Operating today as Teledyne Optech, the company鈥檚 technologies have been deployed on all seven continents, in space and on the surface of Mars.

Beyond research and entrepreneurship, Carswell was a prominent leader in Canada鈥檚 scientific community. He served as Chair and member of the National Science & Research Physics Committee (1977-81), Chair of the committee on Laser Atmospheric Studies of the American Meteorological Association (1984-86) and president of the Canadian Association of Physicists (1985-86).

He was also a founding member and board director of Ontario鈥檚 Institute for Space and Terrestrial Science (now CRESTech), where he served as principal investigator who oversaw LiDAR atmospheric observatories in Toronto and the Canadian High Arctic.

Inspired by Helen, Carswell and his wife began their philanthropic journey with a $1,000,000 gift to establish a program at the East General Hospital where Helen had trained as a nurse.

After retiring from 91亚色, he assumed the role of president of the Carswell Family Foundation where he supported causes across education, health care, science, engineering and the arts. Carswell鈥檚 philanthropic legacy at 91亚色 was profound.

Over decades of sustained giving, Carswell supported scholarships, observatory infrastructure, public science outreach and three endowed research chairs across the Faculties of Science and Health, and the School of the Arts, Media, Performance & Design.

His support was the driving force behind 91亚色鈥檚 Allan I. Carswell Observatory, home to the largest telescope on a Canadian university campus. The Helen Carswell Chair in Community Engaged Research in the Arts (2016), the Allan I. Carswell Chair for the Public Understanding of Astronomy (2018) and the Helen Carswell Research Chair in Dementia Care (2019) were established to promote research excellence, community engagement and knowledge mobilization.

In 2019, the Helen Carswell STEAM Program for Women was launched to honour Helen鈥檚 legacy as a nurse, entrepreneur and co-founder of Optech.

In recognition of his contributions to science and society, Carswell received numerous honours. He was inducted into the Order of Canada (2005), the Order of Ontario (2021), the University of Toronto Engineering Alumni Hall of Distinction (2006) and the Canadian Academy of Engineering (2011).

He received the John H. Chapman Award of Excellence (2006), Ernst & Young Ontario Entrepreneur of the Year (2009), the Volunteer Award from the Canadian Society of Petroleum Geologists (2010), the C.D. Howe Award from the Canadian Aeronautics and Space Institute (2010) and the Queen Elizabeth II Diamond Jubilee Medal (2012).

He was also appointed a Fellow of the Royal Society of Canada (1984) and a Fellow of the Canadian Aeronautics and Space Institute (1982). In 2022, he was named Philanthropist of the Year by the Association of Fundraising Professionals.

Throughout his long and distinguished career, Carswell exemplified the integration of academic excellence, innovative leadership, public service, and philanthropy.

"He made exemplary and lasting contributions to Canadian science, technology and society at large and remained an enduring inspiration for future generations of scientists, innovators and community leaders at 91亚色 and beyond," says Philipps.

A celebration of life will be held at 91亚色, in the McEwen Auditorium, Schulich Executive Learning Centre, 111 Ian Macdonald Blvd. at 1:30 p.m. on April 19 with a reception to follow.

Two 91亚色 chemists are among the recipients of one of NASA's highest honours for their role in a major North American air quality campaign 鈥 work that could help improve how wildfire smoke risks are understood and communicated in Canada.

Faculty of Science Professor Cora Young and Associate Professor Trevor VandenBoer were recognized through the NASA Group Achievement Award for their contributions to the Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas (AEROMMA) campaign, a joint effort between NASA and the The National Oceanic and Atmospheric Administration (NOAA) to study air quality and climate interactions across North America.

The award is reserved for those who have made exceptional contributions to NASA's mission and scientific endeavours.

AEROMMA combined aircraft, ground-based measurements and satellite observations to study how contemporary emissions from cities and oceans affect air quality and climate. NASA and NOAA approached 91亚色 to lead the Toronto supersite, one of several measurement hubs established in major North American cities to contribute to the campaign's airborne data.

Young served as scientific lead, coordinating a team of 25 to 30 researchers; VandenBoer served as logistical lead, overseeing the physical transformation of 91亚色's rooftop laboratory 鈥 on the Petrie Science and Engineering Building 鈥 to host the research.

Also involved were 91亚色 colleagues Mark Gordon, associate professor at the , and Rob McLaren, professor emeritus in the Department of Chemistry.

Collaborators came from across Canada and internationally, including Environment and Climate Change Canada (ECCC) and the University of 91亚色 in the U.K.

91亚色 graduate and undergraduate students had the opportunity to work on the project with those visiting researchers.

"Our ability to bring together this strong team of researchers allowed us to ensure it was worthwhile for AEROMMA to include Toronto," says Young. "Otherwise, we would have missed out on this unprecedented opportunity to learn about modern air quality here."

The 2023 summer AEROMMA project unfolded during a period of intense wildfire smoke across the region, an unplanned development that offered a rare opportunity for study.

"Wildfires will exacerbate air quality issues," says VandenBoer. "Understanding the chemistry of wildfire plumes arriving in the city is going to be critical to informing the public on when and how to protect their respiratory health."

The existing Air Quality Health Index is not well-suited to wildfire conditions because the smoke differs from the other drivers of urban air pollution.

One of the first papers to emerge from the project, now in its final round of peer review, found that wildfire smoke changed chemically as it travelled, changing how health and climate impacts are understood and communicated.

91亚色 researchers have also been in dialogue with the team behind ECCC鈥檚 2024 Study of Winter Air Pollution in Toronto (SWAPIT). Together, the summer and winter datasets create a year-round picture of urban air quality in Canada鈥檚 largest city that could inform policy on everything from wood-burning smoke to the atmospheric impacts of road salt.

The work also validated NASA鈥檚 TEMPO satellite, a space-based instrument tracking air pollution across North America. Measurements from 91亚色鈥檚 site, alongside NASA research aircraft and ECCC sites, were essential in confirming the satellite鈥檚 early readings, helping move the tool into practical use for ongoing air-quality monitoring and research.

Members of the the Atmospheric Emissions and Reactions Observed from Megacities to Marine Areas (AEROMMA) campaign, a joint NASA-NOAA effort to study air quality and climate interactions across North America.

For 91亚色 graduate students, the initiative created opportunities to build international networks. VandenBoer says students helped host collaborators by familiarizing them with 91亚色鈥檚 facilities and procedures, and in some cases were involved with operating, maintaining and responding to issues with visiting researchers鈥 instruments.

Those connections continued beyond the project. Graduate student Yashar Ebrahimi-Iranpour later spent two weeks collaborating at NOAA鈥檚 Chemical Sciences Laboratory, while graduate student Na-Yung Seoh went on to join an international University of 91亚色-led campaign in Cape Verde.

AEROMMA involved a range of 91亚色 collaborators, including facilities staff, operations teams and University leadership.

"It's a 91亚色 community undertaking," says VandenBoer. "A lot of people wanted to support us, and for no other reason than that's just the type of community that we have."

Young points to why the work is imperative today.

"There are a lot of chemicals being emitted into the environment we can't see or smell or taste," she says. "Just because we can't detect them with our own senses doesn't mean they're not a problem. We need to keep on top of it."

91亚色 is among the recipients of federal clean energy funding, with $695,000 awarded to support research advancing next鈥慻eneration carbon dioxide capture technology at the .

Announced March 27 at 91亚色鈥檚 Markham Campus, Natural Resources Canada will invest $28.9 million in 12 projects across the country to build and deploy clean energy technologies through its Energy Innovation Program.

These investments support efforts to reduce emissions and modernize Canada鈥檚 energy systems as clean technologies advance.

91亚色's project, led by Associate Professor Marina Freire鈥慓ormaly at Lassonde, is one of four initiatives funded in the Carbon Capture, Utilization and Storage stream which supports early research on capturing, moving, story and reusing carbon dioxide.

Freire-Gormaly will focus on developing a carbon capture technology that replaces heat鈥慽ntensive systems with electrochemical and light鈥慸riven processes. By using advanced materials, the technology aims to cut energy use, reduce operating costs and improve performance.

鈥淭his funding allows us to move promising carbon capture ideas from the lab and scale them up, closer to real鈥憌orld use,鈥 says Freire鈥慓ormaly. 鈥淚t supports 91亚色鈥檚 role in developing practical, low鈥慹nergy solutions that can help reduce emissions.鈥

The project, titled 鈥淒evelopment and scale-up of novel solid C02 capture photoelectrochemical active sorbents,鈥 began in 2023 and will continue until March 2027 with a focus on creating and testing new solid materials that absorb carbon dioxide when exposed to light and electricity, instead of through thermal processes.

Freire鈥慓ormaly and her team of researchers 鈥 including co-applicant Assistant Professor Solomon Boakye-Yiadom and other collaborators at 91亚色's Faculty of Science 鈥 have developed new electrode materials using copper, aerogels and specialized coatings to improve performance.

Researchers are using a small, custom-built lab to accurately measure how much carbon dioxide is captured. Findings will help evaluate costs, environmental impacts and carbon emissions, and help determine how sustainable and practical the innovative solvent-based pathway would be at an industrial scale.

鈥淭hese innovations are crucial towards a net-zero energy transition for all Canadians,鈥 says Friere-Gormaly.

Tim Hodgson, minister of energy and natural resources, says the project reflects Canada鈥檚 goal to scale up clean energy and responsibly grow the nation鈥檚 conventional energy industry.

鈥淲e are investing to provide reliable, affordable and clean power across the country that will propel our economic growth, protect affordability for Canadian families and make Canada a low-risk, low-cost, low-carbon energy superpower.鈥

Three 91亚色 researchers will participate in a provincial program designed to strengthen connections between science and policy.

Ciuying Jian (associate professor, ), Trevor VandenBoer (associate professor, Faculty of Science) and Daanish Mulla (postdoctoral fellow, ) are three of 34 delegates selected to engage in dialogue with policymakers during the 2026 Science Meets Parliament 鈥 Ontario Program (SMP-ON).

The event creates opportunities for in-depth knowledge sharing, in which delegates from the academic scientific community gain insights into the legislative process and learn how to effectively communicate research to policymakers.

This is the second year for the Ontario cohort, which is an expansion of the SMP federal program launched by the Canadian Science Policy Centre (CSPC) in 2018. It serves as a non-partisan initiative to benefit scientists, members of provincial parliament (MPPs) and Ontarians.

The three 91亚色 representatives will bring research expertise in water and energy, air quality and chemical instrumentation, and human movement to the Spring 2026 delegation.

鈥淭his initiative is important because it creates a structured space for direct exchange between researchers and policymakers,鈥 says Jian, a professor of mechanical engineering. 鈥淭his type of engagement helps ensure that decisions are informed by evidence and allows researchers to better understand how policy is shaped in practice.鈥

Jian鈥檚 research explores innovative ways to use carbon and water more effectively. Specifically, her research examines how to sustainably produce carbon-based functional materials and use them to clean wastewater and improve environmental monitoring and green energy systems. Her lab also uses computer modelling to understand the behaviour of materials and interfacial systems at a microscopic level.

She plans to highlight to policymakers the importance of supporting both applied and fundamental research and hopes to help build mutual understanding between scientists and MPPs about how each approaches complex decision-making. Jian says she will share insights learned with Lassonde and the wider 91亚色 community, as well as external partners such as the Canadian Society for Mechanical Engineering. She will incorporate these new perspectives into her research practice moving forward, she says.

For VandenBoer, the delegation is an opportunity to help ensure that 鈥渟cience is a non-partisan entity in politics,鈥 and looks forward to scientists and MPPs working together to serve Ontarians

Atmospheric and analytical chemistry is the focus of VandenBoer鈥檚 research at 91亚色, which develops new tools to track nitrogen from use as fertilizer to grow crops to the air, as well as in the air quality of urban environments including indoor spaces. The research team working with VandenBoer studies how these chemicals travel and change from microscopic interactions at atmospheric interfaces to impacts at a global scale.

VandenBoer notes that by giving MPPs access to experts, and CSPC teaching scientists how to translate research for policy relevance, the program ensures that provincial decisions can be grounded in the best available evidence.

鈥淭he collaboration aims to benefit all Ontarians by bringing a wide range of diverse, expert voices into government to solve real-world problems,鈥 says VandenBoer, adding he plans to maintain relationships developed during the delegation.

Mulla, a postdoctoral researcher with Connected Minds at 91亚色, sees the delegation as an opportunity to ensure his research generates evidence that is scientifically rigorous, but also directly actionable for public health policy.

His research investigates how the brain and nervous system control movements. By using advanced computer models, he explores how individuals learn new skills or break old habits, with the goal of finding ways to help people learn physical tasks faster and safely.

"Visible collaboration between researchers and policymakers signals that evidence and governance are working together, not in silos,鈥 Mulla says, adding that he鈥檒l apply what he learns to his teaching and research, and will incorporate findings into lessons about science communication.

By participating in the initiative, 91亚色 researchers will help strengthen connections between science and policy at the provincial level.
