I will have some opportunities for fieldwork with students this summer (2014) at a fossil site in Wyoming where we will be excavating large extinct vertebrate fossils (mammoths, American lions and cheetahs, and other mammals).

2014 research

I am a vertebrate paleontologist and a functional morphologist that specializes in mammalian carnivores. I am interested in how we can examine ecology in both living species and in the fossil record using morphology. I am particularly interested in how climate change and the extinction events at the end of the Pleistocene (10,000 years ago) have affected the morphology and ecology of living and Pleistocene species.
