Biography

Dr. Greg Fairn is a Staff Scientist in the Keenan Research Centre for Biomedical Science at St. Michael’s Hospital. Dr. Fairn is trained in a variety of disciplines including Cell Biology, Immunology, Genetics and Biochemistry. He is an Associate Professor at the University of Toronto in both the Department of Surgery and the Department of Biochemistry. He is also a Member of the Institute of Medical Science, University of Toronto, iBEST and Yeates School of Graduate Studies, Ryerson University.

His research interests are broad but tend to focus on novel aspects of lipid metabolism and cellular signaling in a variety of physiological settings. As such, he has published ~60 peer-reviewed articles, covering a variety of topics including cancer biology, innate immunity and inflammation as well as fundamental studies on cell dynamics, organelle biology, lipid metabolism and chemical biology. Since beginning his lab at St. Michael’s Hospital in the summer of 2012, he has contributed to the training of over 30 students, post-doctoral fellows and visiting medical residents.

Dr. Fairn serves on several academic and governmental review committees, including project grant and graduate student scholarship committees for the Canadian Institutes of Health Research (CIHR) and Alberta Innovates Health Solutions. He also is an editorial board member for the journals Cellular MicrobiologyScientific Reports, and Traffic. Dr. Fairn has received a New Investigator Award from CIHR and an Early Researcher Award from the Government of Ontario to support the establishment of his laboratory. He also holds research grants from CIHR, the JP Bickell Foundation and Natural Sciences and Engineering Research Council of Canada.
