My research uses molecular genetic and ecological tools to inform applied management decisions for endangered and rare species. I study both wild and captive bred populations and work with academics, state biologists, federal biologists, and zoo personnel. My main fields of research are conservation genetics, population genomics, landscape genomics, and applied ecology. I have primarily studied mammals (e.g., bats, bobcats, pangolin, rabbits, tree kangaroos, and white-tailed deer), but I also have worked with other animals, such as anole lizards, brook trout, and mysid shrimp. I am particularly interested in how organisms adapt to their environment, the spatial movement of adaptive and neutral genetic variation, and characterizing an animal’s habitat. One of our main projects is using genetic and ecological tools to inform management decisions for the New England cottontail. We strive to communicate our research results to managers and stakeholders to inform conservation decisions for rare species.
