Director

Luke J Chang, PhD

Luke Chang is an Assistant Professor of Psychological and Brain Sciences at Dartmouth College and directs the Computational Social Affective Neuroscience Laboratory. He completed a BA in psychology at Reed College, an MA in psychology at the New School for Social Research, and a PhD in clinical psychology and cognitive neuroscience at the University of Arizona with Alan Sanfey, PhD. Luke completed his predoctoral clinical internship training in behavioral medicine at the University of California Los Angeles and a postdoctoral fellowship at the University of Colorado Boulder under the mentorship of Tor Wager, PhD. His research program is focused on understanding the neurobiological and computational mechanisms underlying social interactions. He is actively involved in the emerging fields of social, affective, and decision neurosciences and uses advanced models to understand how we learn and make decisions in social contexts and how pain and emotions can be regulated through social interactions. When he’s not at the lab, Luke enjoys cooking, bike riding, producing music, and learning new statistical techniques and technical computing skills.

Postdocs

Seth Frey, PhD

Seth Frey studies human decision behavior in complex social environments, approaching computational social science from the perspectives of behavioral game theory and cognitive science. His work integrates laboratory experiments, very large behavioral datasets, and computational models. Presently, Seth is a Postdoctoral Fellow at Dartmouth College’s interdisciplinary William H. Neukom Institute for Computational Science. Before Dartmouth, he was a postdoctoral researcher at Disney Research, a part of Walt Disney Imagineering, where he applied his expertise to both theoretical and practical questions about user-generated content. During that time he was also a Lecturer at the Swiss Federal Institute of Technology (ETH Zürich). In 2013, he earned a Ph.D. in Cognitive Science and Informatics at Indiana University. He earned a B.A. in Cognitive Science from the University of California at Berkeley in 2004.

Pin-Hao Andy Chen, PhD

Andy completed a M.S. in clinical psychology at National Taiwan University, and a Ph.D. in cognitive neuroscience at Dartmouth College. One of his research lines is using brain-imaging method to develop effective self-regulatory improvement techniques. A separate line of his research is to understand the acculturation processes within immigrants using a brain-as-predictor approach. Extending from his research on acculturation, he will start his new research on how culture influences social interaction and symptom expression using a computational approach.

Graduate Students

Eshin Jolly

Eshin graduated with a BA from the University of Rochester where he studied the origins of conceptual knowledge with Professors Jessica Cantlon and Brad Mahon. After graduating, he spent two years as a research assistant and lab manager at Harvard with Professor Jason Mitchell, studying mental state inference and social cognitive changes in older adults. At Dartmouth his research involves the application of statistical models to the study of social perception. Specifically, he is interested in understanding predictive inferences based on behavior and animacy, and broadly, the cognitive and neural computations we employ in service of detecting and connecting with other agents. In his free time Eshin can be found writing/playing music, falling down some rabbit-hole of statistics or intensely "studying" craft beer, the last of which is often informs the first two.

Jin Hyun Cheong

Jin graduated from Princeton University with a BA in Psychology and certificates in Neuroscience and Finance. After graduation, he worked as a research assistant and lab manager for Professor Matthew Botvinick at the Princeton Neuroscience Institute, where his research involved investigating the computational and neural foundations of human decision making and planning. At Dartmouth, he is interested in applying computational, behavioral, and neuroimaging methods to investigate how emotions and social cognition influence people’s economic choices and behavior. His non-academic life involves cycling, snowboarding, and cooking spicy food.

Emma Templeton

Emma graduated from Harvard where she worked with Jason Mitchell and Diana Tamir. After graduation, Emma worked as the lab manager in Jamil Zaki's Stanford Social Neuroscience Lab. Emma is both personally and scientifically interested in figuring out what makes conversation "good." That is, what features of an individual, a dyad, and the conversation itself best predict when people feel connected to each other? Outside of the lab, Emma enjoys organized activities, organizing activities, and digiorno pizza.

Lab Manager

Antonia Hoidal

Antonia is a recent graduate of Dartmouth College, where she majored in Psychology and minored in Economics with additional studies in Russian. A global thinker with a passion for human rights, she seeks to understand how individuals and organizations operate and make decisions across various cultures and social paradigms. Her current academic interests include understanding the influence of emotions, culture, and social norms on decision-making. Over the last few years, through academic funding and fellowships, she has been able to work and study abroad five times, traveling to over 50 countries. Following her time in the lab, Antonia intends to pursue a PhD in cognitive psychology and hopes to continue her travels. When she’s not in the lab, Antonia enjoys snowboarding, backpacking and playing the violin.

Research Assistants

Arati Gangadharan

Arati is an undergraduate student at Dartmouth College studying neuroscience and public policy. After graduating, she hopes to attend medical school and continue exploring public mental health practice and policy. Arati is also interested in dance and music.

Meredith Geaghan-Breiner

Meredith is an undergraduate student in her third year at Dartmouth, majoring in Psychology with a minor in French. Her interests include psychopathology, affective psychology, and social psychology. She is particularly interested in exploring the representation of affective and emotional states in the brain. After Dartmouth, she hopes to conduct research for several years before attending medical school and pursuing a career in clinical psychiatry. In addition to her work in the lab, Meredith serves as a Teacher’s Assistant in the French department, and in her free time enjoys music and running.

Hirsh Elhence

Hirsh is a junior looking to get his A.B. in Neuroscience because he is generally interested in exploring how social forces shape our subconscious brain. After Dartmouth College, Hirsh would like to spend some time exploring the world, before embarking on a fulfilling journey through medical school. In his free time, Hirsh enjoys playing guitar, making music on his computer, spending time with his friends and family, and leading a sedentary lifestyle.

Eric Andrews, MA

Eric is a psychotherapist in private practice and started working with Dr. Chang as a research assistant in early 2015. He is a graduate of the University of New Hampshire where he completed his B.A. in Psychology and his M.A. in Clinical Psychology. Before approaching psychology, his background included significant work as a designer/illustrator as well as application programmer and web developer. Eric’s primary psychological interests are in affective neuroscience; specifically the interaction between limbic and pre-frontal structures in regard to decision making and the development/maintenance of belief systems. He intends to apply to a Ph.D. program for the 2016 school year.

Sam Greydanus

Sam is an undergraduate physics student at Dartmouth College. His research experience covers particle physics, deep learning, and the neuroscience of human interactions. He is particularly excited about recurrent neural networks, deep generative models, and the scientific applications of deep learning.  Sam enjoys running with the Dartmouth Endurance Racing Team and talking to complete strangers about why physics is awesome! In his free time, he climbs, fishes, and spends time outdoors.  Before Dartmouth he raised pigs in the countryside around Corvallis, Oregon.
