Join us TODAY at 1PM ET for our #IDEpi Seminar presented by Erin Mordecai, Associate Professor in the Biology Department at Stanford University. Register for Zoom at hsph.me/IDEPI25
More than warming: climate change is transforming the landscape of vector-borne diseases. CCDD ID Epi Seminar Series. Thursday, May 8, 2025. 1-2PM ET. FXB G12 and Zoom. Erin Mordecai’s research focuses on the ecology of infectious disease. She is interested in how climate, species interactions, and global change drive infectious disease dynamics in humans and natural ecosystems. This research combines mathematical modeling and empirical work. Erin finished her PhD in 2012 at the University of California Santa Barbara in Ecology, Evolution, and Marine Biology. She then completed a 2-year NSF postdoctoral research fellowship in the Intersection of Biology and Mathematical and Physical Sciences and Engineering at the University of North Carolina at Chapel Hill and North Carolina State University. Erin has been at Stanford since January 2015. Speakers will share their own perspectives and do not speak for Harvard.
