Dr. Tommy Alain

Biography

Research

Dr. Tommy Alain is a Scientist at the Children’s Hospital of Eastern Ontario (CHEO) Research Institute and Associate Professor in the Department of Biochemistry, Microbiology and Immunology at the University of Ottawa. His training is in virology, innate immune responses, cell biology, and oncology. Dr. Alain received his B.Sc. (2000) in Biochemistry from Université Laval in Québec City and his Ph.D. (2007) in Medical Science from the University of Calgary. During his Ph.D., Dr. Alain studied the virology and the oncolytic potencies of reovirus, vesicular stomatitis virus, herpes simplex virus and myxoma virus against brain cancers. He then pursued post-doctoral work at McGill University studying mRNA translational control and the mammalian target of rapamycin (mTOR) signaling pathway, linking both viral immunity and oncology research. Dr. Alain’s current research at the CHEO Research Institute and the University of Ottawa focuses on exploiting translation initiation factors and downstream effectors of mTOR complex 1 (mTORC1) to modulate innate immune responses to pathogens, and to augment the anti-proliferative efficacies of cancer therapeutics.
