My research focuses on understanding the neurobiological and psychological processes underlying social interactions.  I am interested in understanding how emotions and expectations are represented in the brain and impact how we make decisions and learn in social contexts. We use computational techniques such as utility theory, reinforcement-learning, and machine-learning to develop models of these complex processes and validate our models using behavioral, psychophysiological, and neuroimaging experiments.  One application of this approach is to create a better understanding of the mechanisms by which psychosocial treatments influence our mental and physical health.
