Research in my laboratory is focused on understanding the macroevolutionary-scale patterns of structure-function relationships in mammals and other vertebrate groups. Projects in my lab include analysis of variables such as diet, evolutionary relationships and non-masticatory functional constraints and their interplay on the structure and function of the skull as a feeding tool. I use methodologies such as landmark-based shape analysis (geometric morphometrics), model-based assessments of feeding performance (finite element analysis) as well as experiment-based model validation approaches (mechanical testing and kinematics analysis). I also conduct field-based and collection-based research on extinct mammal groups to understand the influence of inter-continental dispersals on the evolution of predator lineages. My fieldwork areas including Wyoming (Eocene), Inner Mongolia (Neogene), Tibetan Plateau (Neogene), Mexico (Neogene), and southern China (Paleocene).
