Dr. Sapna Sharma is an Associate Professor in Biology at York University. Sapna studies the effects of climate change, invasive species, and pollution on lakes. She is investigating how these effects are manifested through water quality, fish populations, water temperatures, and lake ice. With a young, a lot of Sapna's time away from science is spent with her family. It has been fun to go to music classes and swimming classes together. She received her PhD in Ecology and evolution from the University of Toronto and completed postdoctoral fellowships at the University of Montreal and the Center for Limnology at the University of Wisconsin-Madison. She served on the faculty at Loyola before joining the faculty at York where she is today. Sapna is also founder of a science outreach program at York University for refugee children called SEEDS. She is with us today to tell us all about her journey through life and science.
