I have worked on the reproductive behavior and physiology of yellow-bellied marmots and I most recently focused on patterns of hibernation in woodchucks. Currently, I am investigating the vocal behavior and distribution patterns of tree squirrels inhabiting an urban landscape. I have worked over the years with many students on a variety of projects centered in behavioral ecology and I welcome any students interested in seeking research experience in the field or lab setting.
