I am an evolutionary biologist fascinated by macroevolution, and the aim of my research program is to elucidate the deep time histories of diverse clades. I perform hypothesis-based research, with mammals (both fossil and modern) being my preferred study organisms. My studies have employed a variety of innovative approaches, including biomechanical models, paleoecological analyses, phylogenetic comparative methods, and morphometrics. My research is largely based on original data obtained from museum collections, and I have been active in numerous fieldwork projects to help grow these collections
