Joe DeMarchi (PhD Student)

I am broadly interested in incorporating complex host-parasite interactions into our general understanding of infectious disease. In particular, my research will investigate host-parasite community dynamics specifically how host identity, communities and landscapes can shape disease outcomes. I hope to incorporate heterogeneity among species and landscapes in multi-host communities to predict areas of disease emergence


Sarah Schrock (Master’s Student)

I have a BS in Biology from Olivet Nazarene University and an MS in Epidemiology from the University of Colorado. I worked for a couple of years as an epidemiologist at a hospital in Denver and later at the New Mexico Department of Health. For several years, I have been interested in shifting my career from public health to wildlife, focusing on disease ecology. In the summer of 2021, I had the pleasure of working on a statewide assessment of alligator snapping turtles with the University of Houston. Since then, I’ve been working as an assistant keeper at Zoo Knoxville. I am honored to be joining UT’s FWF Department and having the opportunity to study the fungal pathogen Batrachochytrium dendrobatidis (Bd) in amphibian species. My research will combine fieldwork and mathematical modeling to better understand the factors influencing long-term Bd persistence in amphibian species in eastern Tennessee.
