B.A., Biology, Colby College


Jen Jost’s research interests include the physiological ecology of marine and aquatic invertebrate species. Past research focused on the heat tolerance of marine bivalves and crustaceans.  Her current research examines the cellular effects of environmental stressors in the zebra mussel, an aquatic invasive species in the Illinois River. Since 2010, Jen has mentored 16 undergraduate students, one graduate student, and three local high school students in her research laboratory.


Courses taught for biology majors include Introduction to Biology (BIO 150), Molecules to Cells (BIO151), Comparative Animal Physiology (BIO381), Environmental Physiology (BIO417) and a Special Topics course in Marine Biology (BIO475). Courses for non-majors include Biotechnology and Society (BIO 301) and Human Histology (BIO351) and multiple courses for the College of Education and Health Sciences including Introduction to Cell Biology (BIO111), Human Anatomy and Physiology I (BIO230) and Human Anatomy and Physiology II (BIO232).
