Meet Our Researchers
Dr. Joseph Cafazzo
Dr. Joseph Cafazzo is an associate professor at the University of Toronto and executive director of biomedical engineering at the University Health Network. He is collaborating with manufacturers of diabetes devices to ensure they are compatible with computers, smartphones and each other – making it easier for people to manage their type 1 diabetes. Dr. Cafazzo is also working on new features for bant – a unique, free smartphone application he launched in 2010 with the support of TELUS Health Solutions that offers a simpler and more attractive option for daily diabetes management.

Dr. Jayne Danska
Dr. Jayne Danska holds The Anne and Max Tanenbaum Chair in Molecular Medicine. She is a professor at the University of Toronto Faculty of Medicine and a senior scientist at The Hospital for Sick Children. Her research addresses the idea that the dramatic increase in autoimmune and inflammatory diseases over the past 50 years results, in part, from changes in our exposure to microbes. She is studying the role of the community of microbes that inhabit the human intestine (the microbiome) in altering risk for, and the progression of, type 1 diabetes. The ultimate objective of her work is to identify new therapeutics to prevent the disease.
Dr. Denice Feig
Dr. Denice Feig is a staff endocrinologist and head of the Diabetes in Pregnancy Program at Mount Sinai Hospital and the University Health Network. She is investigating whether the use of continuous glucose monitors before and during pregnancy can improve the health of women and babies affected by type 1 diabetes. Dr. Feig is also the principal investigator of a multicentre study looking at adding metformin to insulin in women with type 2 diabetes in pregnancy and following their children.
Dr. Timothy Kieffer
Dr. Timothy Kieffer is a professor in the Department of Cellular and Physiological Sciences and the Department of Surgery at the University of British Columbia. He is manipulating stem cells into glucose-responsive insulin-producing cells that can then be transplanted into people with type 1 diabetes. This procedure could one day reduce or eliminate the need for daily insulin injections.
Dr. Gregory Korbutt
Dr. Gregory Korbutt is a professor of surgery at the University of Alberta. He is using different techniques to safeguard cells with the goal of developing a more accessible source of insulin-producing tissue for transplantation into patients with type 1 diabetes. Dr. Korbutt and his team are using their new 3D ‘scaffolding’ technology to make islet transplants more widely available and functional.The scaffolding technology can help improve blood flow and oxygen to the transplant site, as well as allow incorporation of proteins into the scaffolds that will help keep the cells healthy. Find out more about Dr. Korbutt’s research.
Dr. Megan Levings
Dr. Megan Levings is an investigator at British Columbia's Children's Hospital and a professor in the Department of Surgery at the University of British Columbia. She is developing a test to monitor the health of T regulatory cells, which help control the type 1 diabetes autoimmune attack.
Dr. Farid Mahmud
Dr. Farid Mahmud is a staff physician in the Department of Endocrinology at The Hospital for Sick Children and an associate professor of pediatrics at the University of Toronto. He is identifying young people with type 1 diabetes (T1D) at high risk of developing kidney and heart complications, and assessing whether medications for lowering cholesterol and treating high blood pressure can serve as deterrents. Dr. Mahmud is also screening people with T1D for celiac disease, and evaluating whether a gluten-free diet improves diabetes management.
Dr. Maria Cristina Nostro
Dr. Maria Cristina Nostro is a scientist at the Toronto General Hospital Research Institute and an assistant professor in the Department of Physiology at the University of Toronto. She is also a principal investigator at the McEwen Centre for Regenerative Medicine and holds the Harry Rosen Chair in Diabetes and Regenerative Medicine Research. By combining expertise in stem cells and developmental biology, she is pioneering novel transplantation approaches aimed at creating an ideal environment for the survival of stem cell-derived insulin-producing cells.
Dr. Rémi Rabasa-Lhoret
Dr. Rémi Rabasa-Lhoret is an endocrinologist and supervisor of the external artificial pancreas research project at the Montreal Clinical Research Institute where he is testing this device for patients with type 1 diabetes (T1D). Two configurations of the artificial pancreas are being assessed: one that infuses insulin, and another that infuses insulin and glucagon (a hormone that can help raise blood sugar and reduce the risk of hypoglycemia). The artificial pancreas could help people with T1D reach target blood sugar range, thereby decreasing the risk of chronic complications and simultaneously reducing the risk of hypoglycemia, which remains the most common adverse effect of insulin therapy.
Dr. Michael Riddell
Dr. Michael Riddell is a professor in the School of Kinesiology and Health Science at York University. His research is focused on reducing excessive levels of insulin and preventing hypoglycemia in people with type 1 diabetes (T1D). Dr. Riddell led a team of researchers to determine guidelines for exercising safely with the condition. He is also a member of a multidisciplinary team working to design the T1D Performance in Exercise and Knowledge (PEAK) Program that will provide people living with T1D the tools they need to better manage their disease, including access to international educational events hosted by global experts and online materials. Dr. Riddell is also experimenting with a new drug that halts hypoglycemia, which will soon be ready for clinical trials. As a senior scientist at LMC Diabetes & Endocrinology, he oversees studies on optimizing insulin management for exercise in active people living with T1D.

Dr. James Shapiro
Dr. James Shapiro, a multi-organ transplant surgeon at the University of Alberta, led the team that introduced the Edmonton Protocol, which optimized the medication given with islet transplants. Currently, he is conducting a phase I clinical trial on transplants using a product containing pancreatic progenitor cells (the precursors of stem cells) housed inside a device that protects them from being destroyed by the immune system. Dr. Shapiro is also leading clinical trials to switch off autoimmunity and repair injured beta cells at the time of diagnosis of type 1 diabetes. These promising tools could one day elminate the need for insulin injections.
Dr. Paul Fernyhough
Dr. Paul Fernyhough is a professor at the University of Manitoba and the director of the Cell Biology of Neurodegeneration Lab at St-Boniface Hospital Research Centre in Winnipeg. His research has focused on the neurodegenerative disorders of the peripheral and central nervous systems in patients with diabetes.
