I am a fifth year graduate student working with Dr. Todd Heatherton. My research focuses on understanding the neural bases of social behavior and social interactions. I use both neuroimaging and behavioral techniques to characterize the rewarding value of social connections and the effects of social exclusion on cognition and behavior. Prior to coming to Dartmouth, I graduated from Bowdoin College in 2007 and then spent two years working as a Research Assistant at Harvard University in Randy Buckner’s Cognitive Neuroscience Lab.
