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, kayaking, skiing, bike riding, producing music, and learning new statistical techniques and technical computing skills.


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.

Graduate Students

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. Here at Dartmouth, Emma works with both Thalia Wheatley (primary advisor) and Luke Chang. Emma is 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.

Marissa Clark

Marissa graduated from UCLA with a BS in Cognitive Science and a minor in Neuroscience. After graduation, she worked as a lab manager for Jamil Zaki's Social Neuroscience Lab at Stanford University. At Dartmouth, she is interested in studying social cognition and communication using behavioral, computational and neuroimaging methods.

Wasita Mahaphanit

Wasita graduated from Brown University with a BS in Cognitive Neuroscience, where she worked with Amitai Shenhav and Romy Frömer. After graduation, she worked as the lab manager of Michael J. Frank’s Laboratory of Neural Computation and Cognition where she investigated the behavioral and computational mechanisms underlying learning and decision-making under uncertainty in healthy adults and patients with obsessive compulsive disorder. At Dartmouth, she plans to work on projects related to how we learn social cognitive maps and use this information in how we communicate and make decisions. To explore her interests, she aims to use a combination of behavioral experiments, computational modeling, and neuroimaging. Outside of academics, Wasita enjoys scouring Spotify for new releases and training in aerial hoop.

Bryan González

Bryan received his BA and MA from NYU. After a stint as a producer in creative media industries, his interest in research began in the Social Relations Lab at Columbia University studying speech mimicry. He later spent time learning polysomnography at Weill Cornell before coming to NYU Langone as a senior research coordinator. There, his efforts focused on finding biological markers of PTSD. At Dartmouth, Bryan is primarily interested in the computational mechanisms underpinning theory of mind across perceptual, behavioral and cognitive domains. His research is strongly influenced by reinforcement learning models, and probes mental state attribution in action understanding, preference learning, and anthropomorphism in human-robot interaction. Bryan is also passionate about promoting diversity in STEM education. In his free time, he loves running, live music, and curling up with his cat, “Puppy”.

Tiankang Xie

Tiankang graduated from the University of Wisconsin-Madison with BS in Mathematics and Statistics, minoring in Computer Sciences. While in college, Tiankang did research with Prof. Moo K Chung at UW-Madison working on statistical algorithms for big fmri data. Before finally landing at cosan Lab, Tiankang spent time doing research rotations on cancer epigenetics, proteomics and epilepsy. At Cosan Lab, he is generally interested in BCI and computational neuroscience, especially on how to quantitatively assess emotions and social decisions. In his free time, Tiankang loves cooking, hiking and cycling.

Lab Manager

Amanda Brandt

Amanda received her BA in Psychology from Harvard University in 2018. As an undergraduate, she worked as a research assistant with Professor Leah Somerville studying reinforcement learning and decision making during adolescence. At Dartmouth, Amanda is interested in applying computational, behavioral, and neuroimaging methods to investigate how emotions influence decision making and social interactions. Specifically, she is interested in understanding how symptoms commonly associated with post-traumatic stress disorder and depression (i.e., dysregulation of emotions, negative affect, perceived isolation, etc.) can influence an individual’s emotional experience and social connectedness. Additionally, she is interested in probing deeper into the intersection of technology and health, and its potential for experimental therapeutic approaches. In her free time, Amanda enjoys being outdoors, finding new music, laughing at terrible puns, and asking strangers if she can pet their dogs.
