Outstanding levels of biotic perturbation are predicted to occur under future climate change, yet data regarding distributions, dispersal, and adaptive capacities are lacking for many species. I study patterns of neutral and adaptive genetic diversity in natural populations to understand how biodiversity is generated and responds to environmental change. The unifying objectives of my research include (1) quantifying the impacts of landscape features, climate change, and human impacts on species ranges and patterns of gene flow, and (2) characterizing and identifying the types and sources of adaptive genetic variation that shape species ranges. My work is conducted on a variety of empirical systems, including insects, frogs, and plants. My passion for conserving biodiversity has motivated me to combine elements of basic and applied research in my research program. I am currently a PERT postdoctoral research fellow in the Dlugosch Lab in the Ecology and Evolutionary Department at the University of Arizona.
