Barrile_GabeGabe Barrile, Postdoc. Gabe is some version of an applied quantitative ecologist. He works at the intersection of disease ecology, population demography, and animal behavior, using data science techniques to provide evidence-based solutions to conservation challenges. Gabe has worked in several wildlife disease systems, from chytrid fungus in amphibians to sylvatic plague in prairie dogs. At the University of Wyoming, Gabe will explore the extent to which animal movement data can be used to infer behavioral states such as infection with emerging diseases. For instance, Gabe will use GPS collar data from migrating ungulates to determine whether movement signatures can predict individual infection status with chronic wasting disease. Outside of work, Gabe enjoys playing basketball, looking for beaver ponds, and watching the Golden Girls. Google Scholar page: https://scholar.google.com/citations?user=lFpoeToAAAAJ&hl=en&oi=ao

Molly Caldwell,mcaldwell_pic PhD student. Molly grew up in southwestern Colorado and has a BA in Integrative Biology from the University of California, Berkeley. Her PhD research focuses on ungulate (bison, elk, mule deer, pronghorn, and bighorn sheep) migrations in the Greater Yellowstone Ecosystem. She will be investigating the community and movement ecology of these species to help understand why a large diversity of movement strategies exist among sympatric ungulates. Previously, Molly worked as an Environmental Scientist with the California Department of Fish and Wildlife where she conducted habitat and wildlife monitoring on state lands and analyzed camera and GPS telemetry data to investigate wildlife use of highway crossings. In her free time, Molly enjoys hiking in the mountains and traveling.

Mike Laforge, Postdoc. Mike has a PhD from Memorial University in St. John’s, Newfoundland, Canada. Mike’s research focuses on how migratory animals deal with inter- and intra-annual variation in resource phenology. His research aims to bridge behavioral and spatial ecology by examining consistent individual differences in migratory behavior. His research at the University of Wyoming focuses on how individuals acclimate—or how populations might adapt—to changing environmental conditions by looking at how individuals acclimate their migration and resource selection behavior as a function of the timing of spring green-up. Mike enjoys hiking, canoeing and exploring new places. Mike’s website: https://mammalspatialecology.weebly.com
