目前的研究
Using non-invasive genetics to diagnose Northern bog lemming occurrence: Northern bog lemmings are a state threatened species in Maine. We know very little about their behavior, ecology, or even their distribution. My students and I are working in the field and in the lab to develop a molecular tool that will allow us to distinguish the threatened Northern bog lemming from its congener, the putatively more-common Southern bog lemming. This project is the first step in improving our understanding of 1) where Northern bog lemmings are, 2)他们在做什么, 3)如何更好地保护它们.
Investigating grey seal food habits: Grey seals are in the process of an impressive comeback in numbers, and concerns are being raised that grey seals are more and more competing with commercial fisheries operations for desirable groundfishes like cod. My colleague in the School of Marine Programs, Dr. 凯瑟琳小野, and I along with our students have developed and are using molecular tools to determine food habits of the now abundant grey seals.
Scavengers and foraging risk: The world outside can be a scary place. We know that most animals, if given the chance, will engage in foraging on carrion (i.e.(动物尸体). 然而, 动物所做的决定, 具体情况具体分析, to engage or not to engage in foraging on carrion are still a mystery. My students and I are investigating foraging decisions made by scavengers when faced with a potentially free meal associated with carrion.

研究兴趣
My scholarship in animal behavior can be divided into two broad categories. My students and I conduct applied research that seeks to inform efforts to conserve wildlife and we conduct basic research investigating facets of foraging behavior including scavenging ecology.
