Peter Sokol-Hessner

Peter received his Ph.D. in Psychology from New York University in Elizabeth Phelps' lab. He did postdoctoral training with Antonio Rangel at Caltech, and then with Nathaniel Daw and Elizabeth Phelps at NYU. In his work, he enjoys integrating the perspectives and methods associated with different fields, including cognitive psychology, cognitive neuroscience, and microeconomics, to understand how we assess value, how we use value to guide behavior, and the ways that emotion is integrated into those processes.

Eric Andrews

Eric is a research assistant and lab manager. Previously a part-time RA for Dr. Luke Chang’s lab at Dartmouth College, he was involved in projects that explored the use of machine-learning methods to predict behavioral and neural reaction from sparse sets of response data. His research interest is in the neural activity that addresses situationally-inappropriate behavioral reactions due to the impact of emotional state on context recognition systems.

Eric is a graduate of the University of NH where he received his B.A. in Psychology and his M.A. in Counseling. He has been working as a psychotherapist in private practice since 2008 and maintains a small client base helping individuals with anxiety and trauma-related disorders.
