Elisabeth Simonin

Dr. Elisabeth Simonin teaches microbiology for nursing students and science majors. She is amazed by the intricate interactions between the immune system and the outside world and loves to help students explore their curiosities about biology, immunity, and microbes. Her doctoral research studied what causes allergic reactions in humans (and in horses!), and her post-doctoral research studied how pollution exposure changes the immune system. In her free time, she loves to be outside and in nature — hiking, swimming, canoeing, gardening, skiing — with her family and friends. Come say "hi"!
