Paradyse-2022---resized.jpg

Paradyse Blackwood
Ph.D. candidate, NSF Graduate Research Fellow

Paradyse is interested in how environmental variation (e.g. temperature change), anthropogenic stressors, and disease interact to shape the health and abundance of amphibian species. They are studying how varying temperatures interact with road salt pollution to impact host-parasite interactions and how disease can influence species invasions.

Kurt Lutz
Ph.D. student

Kurt has a bachelor's degree (and Master's degree in progress) from San Francisco State University. For his master's, he studied the effect of biodiversity on disease risk in pond systems with protected species in California. He also previously worked on several land management/sensitive species programs in the Bay Area as a biological consultant.

Aura Muñiz Torres
Ph.D. student, Purdue Doctoral Fellow

Aura has a bachelor’s degree from the University of Puerto Rico Mayagüez and a master’s from the University of Massachusetts Boston. Her research these past years has been focused on amphibian disease ecology. For her PhD she wants to focus on disease dynamics interactions within amphibian community assemblages, especially focused on conservation and disease mitigation strategies.
