Research Interests
My dad was a high school science teacher and introduced me to science at a very young age. There was always fun experiments going on at home and I was hooked after he showed me a paramecium slide with our microscope at home. I fell in love with scientific research during my undergraduate honours project working on insect pathogenic fungus. I wanted to continue academic research for my M.Sc. degree and had the opportunity to study the epidemiology of West Nile virus in Ontario, Canada. I wanted to further my understanding of West Nile virus and for my Ph.D. research I studied the biochemical mechanisms of the West Nile virus protease. From here I changed gears and decided I wanted to learn something totally new for my postdoctoral training. I had the opportunity to learn immunology and focused my research on the impact sepsis has on CD8 T cell responses to infection. This experience opened up a whole new world and I fell in love with CD8 T cells. My current research in the Richer lab focuses on furthering our understanding of CD8 T cell biology in context of infectious models and disease. When I'm not in the lab I enjoy live music, movies, watching TV, experimenting in the kitchen, playing basketball and hanging out with Milou.
