Hector Zumbado-Ulate
Ph.D. candidate

Hector is interested in the effects of parasites on inter-specific competition. He is studying how parasites might mediate competition in amphibians, affecting the recovery of susceptible populations after epidemics.

Spencer Siddons
Ph.D. candidate

Spencer is interested in amphibian ecology, disease dynamics, and conservation. He plans to investigate the effects of environmental stressors on host infection risk and the pathogen themselves. Personal website: www.spencerrsiddons.wordpress.com.

Paradyse Blackwood
Ph.D. student

Paradyse is interested in how environmental variation (e.g. temperature change), anthropogenic stressors, and disease interact to shape disease dynamics in amphibian species. She plans to study how varying temperatures interact with road salt pollution to impact host-parasite interactions.

B.S.: Binghamton University

Kacie Jonasen
Research technician

Kacie earned a B.S. in Zoology from Michigan State University and is working toward a M.S. in Natural Resources and Environmental Sciences from the University of Illinois at Urbana-Champaign. In the Searle lab, Kacie will continue her work with Daphnia, and hopes to incorporate amphibians in future projects. ​
