Areas of Interest and Expertise​

My background is in terrestrial wildlife ecology with a focus on carnivores (primarily bears and bobcats) and harvest, though my interests vary widely. I have interest in exploring both the lives and deaths of wildlife and how individual contexts scale up to have population level effects. This encapsulates both the contextual decisions of individual animals and how we manage and conserve their populations. I have researched several themes, including animal movement, connectivity, sociality, carcass ecology, and the effects of harvest. Moreover, I have utilized a multitude of data collection methods (e.g. location data, genetics, isotopes) and statistical approaches to answer research questions under these themes. My overarching aim is help provide pragmatic answers to (1) applied questions and (2) contribute to the ever-advancing suite of data collection and analytical tools available to practitioners. Moreover, I hope to (3) help bridge the knowledge gap between wildlife science, research findings, and people.

CPW website species information: Snowshoe HareUnderstanding and monitoring snowshoe  href="https://authorcpw.state.co.us/learn/Pages/SpeciesProfiles.aspx?species=Hare">hare​ density in Colorado is important because hares comprise 70% of the diet of the state-endangered, federally threatened Canada lynx. Forest management is an important driver of snowshoe hare density, and all National Forests in Colorado are required to include management direction aimed at conservation of Canada lynx and snowshoe hare.
