Who and What
I am a research scientist with the United States Geological Survey (USGS), Assistant Unit Leader at the Colorado Cooperative Fish and Wildlife Research Unit, and an Associate Professor in the Department of Fish, Wildlife, and Conservation Biology and a faculty member of the Graduate Degree Program in Ecology at Colorado State University.
My focus is on collaborative science:
With my lab and colleagues - we work with scientists and resource and land managers to help learn through data to provide inferential or predictive knowledge or decision-support that is used for empirically informed conservation management of biodiversity.
Our research focus includes
- Wildlife Population Demography and Distribution
- Conservation Decision Making
- Animal Behavior (especially on the diel niche)
- Hierarchical Bayesian Modeling
- Animal Movement and Habitat Selection
- Optimal Prediction via Statistical Regularization

- New OA Publication: A model-based hypothesis framework to define and estimate the diel niche via the ‘Diel.Niche’ R package from the Global Animal Diel Activity Project. Download. We propose a conceptual and modeling framework to connect data and hypotheses to make inference about animal diel phenotypes (e.g., diurnal, nocturnal). The Diel.Niche R package can be found on Github and a shiny version can be found here. We also wrote a blog about our paper that is intended for a more general audience.
