I am a post-doctoral researcher with a Fellowship in Research and Science Teaching at Emory University. My research interests are in the decision-making processes of nonhuman primates under circumstances of risk. I use behavioral economics as a platform for which to explore these issues. Currently, I am working on a series of gambling style tasks to elucidate risk preferences in our closest living relative, the chimpanzee. I am particularly interested in how these decision-making processes are influenced by the social dynamics within chimpanzee groups.
