I broadly consider myself as a paleobiologist and ecologist studying how species, communities, and ecosystems have responded to both anthropogenic and environmental pressures on a variety of scales. At Yale, I am studying the impacts of human hunting and climate change on the megafaunal extinction in India. I use tools including faunal analysis, stable isotopes, bone surface modification, and geochronology to understand the anthropogenic and environmental context of this extinction. This recent extinction of large terrestrial vertebrates has been the focus of paleontological, archeological, and ecological research for decades, but the causes of the extinction are poorly understood in some of the most biodiverse regions of the world, like the Indian Subcontinent. India unlike large parts of the world, retains several species of large mammal like rhinos and elephants, and I am exploring why so many large species survive in this region.
I received my B.A. in Biology from Reed College, and an M.S. and Ph.D. in Environmental Science and Policy from George Mason University. While my bachelors and masters research focused on the developmental plasticity of frogs and the community ecology of Caribbean coral reefs respectively, my doctoral research was centered around the paleoecology of mammals over the last 5 million years. After completing my Ph.D., I was awarded the Deep Time – Peter Buck Fellowship at the Smithsonian’s National Museum of Natural History where I conducted research on the size structure of the herbivore guild through time and the evolution of large mammals like horses and elephants. In addition to my research, I have developed public education and science communication content based on natural history for the Smithsonian, and am actively involved in a number of science outreach projects.
