Katrina Cook

Katrina Cook joined the Chalfoun lab in the fall of 2019. She is pursuing her master’s degree with research focused on habitat selection and quality of wood frogs (Lithobates sylvaticus) in the Snowy Mountains of Wyoming. Katrina received her B.S. in Wildlife Conservation at Juniata College in Huntingdon, PA in 2014. During the following 5 years she worked multiple field technician jobs working with reptiles and amphibians across 6 different states, including Wyoming. She has worked with sea turtles, amphibians, and gopher tortoises in Georgia, dunes sagebrush lizards in Texas, invasive reptiles in southern Florida, to statewide amphibian and reptile surveys in Wyoming for the Wyoming Game & Fish Department. Additionally she has 1.5 years of lab experience working for Dr. Lusha Tronstad at the Wyoming Natural Diversity Database at the University of Wyoming working with aquatic invertebrates on a long-term study assessing the effects of the introduced lake trout (Salvelinus namaycush) on lower trophic levels (benthic macroinvertebrates, zooplankton, and phytoplankton) in Yellowstone Lake at Yellowstone National Park. Some of Katrina’s research interests include food web dynamics, aquatic ecosystems, entomology, and herpetology.
