From Species to Genes

We share the planet with endless forms most beautiful—millions and millions of other species. And there are regular and recurrent patterns in their diversity, distributions, and genetics, both across space and through time. Making sense of the mechanisms that structure these patterns is integral to modern conservation initiatives. From theoretical ecology to conservation genomics, my research focuses on applying the most cutting-edge tools available to best inform conservation of endangered species and entire ecosystems.

Climate change is causing tree lines to advance up mountain slopes, pushing alpine meadows and butterfly populations higher as they track their climatic niche. Connectivity among populations is declining, and translocation of individuals among populations may ameliorate genetic erosion. My genomics research on three alpine butterflies endemic to the Sierra Nevada aims to inform their conservation.
