Research Interests

Fossil vertebrates, stable isotopes, and global change, with emphasis on paleobiology, macroevolution, and paleoecology of Neogene mammals (particularly herbivores) of the Americas

Students Currently Supervised

Larisa Grawe DeSantis (Ph. D., Zoology)
Determining vegetation density in past environments using stable isotopes of tapir teeth. Understanding effects of diet on morphological plasticity of the masticatory complex in mammals.

Joann Labs (Ph. D., Geology)
Quantifying diagenesis in Cenozoic lamnoid shark vertebral centra. How diagenesis effects the oxygen isotope signals preserved in the fossil bone.
