Broadly speaking, my research examines the evolution of mammals in East Africa during the Miocene epoch (25-5 Ma) with a specific focus on the catarrhine primates (Old World monkeys and apes, including humans). Particularly, I am interested in how local environmental and regional climatic changes affected the morphology and locomotor/dietary ecology of African Miocene mammalian species. My research involves 1) studying limb functional morphology in modern primates to reconstruct locomotor patterns and positional behaviors in fossil primates; and 2) reconstructing the paleodiets and paleoenvironments of African Miocene primate and mammalian faunavia stable isotopes and 2D/3D dental topographic metrics.
