My research focuses on the evolution of primates and the relationship between their chewing apparatus and the food they eat.

1. Gross anatomy and fiber architecture of the jaw-closing muscles of primates. This work consists of traditional dissection and description, as well as chemical dissection to measure muscle fascicles. This work has yielded strong patterns in the relationship between muscle dimensions, body size, and diet.

2. The fossil record of primates in the Americas, particularly in the final periods before local primate extinctions. This work includes primate field studies in extreme southern Argentina, the Great Plains of Canada, and basins of western USA.

3. Experimental work on the challenges presented to the chewing muscles by food structural and material properties. I have performed studies of bite size and food properties in a large sample of captive primates. Currently, I am working on testing tooth models as tooth for assessing food material properties using a sample of molars from extant and extinct primates.

4. Biomechanics of the primate skull. This work consists of studies of leverage and excursion in the chewing system using 2D and 3D models. It incorporates variables such as food size and texture.
