Research Associate Scientist

Amrita Nair, PhD 
Associate research scientist
Ph.D. (Duke University)
Amrita received her PhD from Duke University working with Michael Platt. For her PhD work, she examined how social status is represented in the posterior cingulate cortex. She helps to oversee and manage the lab.

Postdoctoral Associates

Philip Putnam, PhD  [google scholar]
Postdoctoral associate
Ph.D. (University of Arizona)
Philip received his PhD in Neuroscience working with Kati Gothard, where he studied neurophysiological and oxytonergic mechanisms underlying social cognition in the amygdala. Philip is interested in how neuromodulators influence neuronal activity in shaping social behaviors.
Chengchi Chu, PhD 
Postdoctoral associate
Ph.D. (Institute of Neuroscience, National Yang-Ming University)
Chengchi received his PhD in Neuroscience working with Chou Hung, where he studied visual receptive field tuning properties of macaque V1 neurons. Chengchi is interested in computational approaches to understanding the neural mechanisms of social behavior.

Graduate Students

Hannah Weinberg-Wolf 
Graduate student
Hannah received her BA degree in Biological Basis of Behavior from Johns Hopkins University and her MA degree in Museum Studies from Johns Hopkins University. She then worked at Princeton University before joining the lab. She is interested in how serotonin regulates socio-emotional processing and effortful control in the brain.
Siqi Fan 
Graduate student
Siqi received her BS degree in Neuroscience and Mathematics from Vassar College. She has research experience in a variety of organisms, from flies to humans. She is interested in causal mechanisms underlying social cognition and social decision-making.
Megha Chawla    [google scholar
Graduate student
Megha received her BA degree in Psychology from University of Southern California, followed by receiving her Masters level degree in Neuroscience from University College London. Afterwards, she conducted several fMRI studies in humans, including working with Ifat Levy at Yale University School of Medicine. Megha is interested in neural mechanisms underlying social decision-making in humans.
Prabaha Gangopadhyay    [website] [google scholar
Graduate student
Prabaha received his integrated BS and MS degrees in Biology from the Indian Institute of Science. For his research prior to joining the lab, Prabaha worked on understanding neural mechanisms of high-level vision in the inferior temporal cortex. Prabaha is interested in neural mechanisms underlying social behavior.
Olivia Meisner   
Graduate student (Gruber Science Fellow)
Olivia received her BS degree in Neuroscience and Behavioral Biology from Emory University. For her research prior to coming to Yale, Olivia studied the development of social attention at Emory and worked on animal models of autism spectrum disorder at MIT. Olivia is interested in neural mechanisms underlying complex social interactions.
Yoonseo Zoh   [website]
Graduate student
Yoonseo received her BA degree in Education from Seoul National University and received a prestigious scholarship for her PhD work funded by Korea Foundation for Advanced Studies. Yoonseo is interested in neural computations underlying social decision-making by applying computational models to human fMRI data.
Emily Siff   
Graduate student (rotating INP student; Gruber Science Fellow)
Emily received both her BS degree in Neuroscience and MS degree in Cognitive Science from Brown Univerisity. Before coming to Yale, Emily was involved in statistical / computational modeling of behavior and neural responses underlying cognitive control and communication. Emily is interested in studying neural mechanisms underlying interactive social processes.
April Pruitt   
Graduate student (co-mentored rotating INP student; Kavli Fellow)
April received her BS degree in Biology from Univerisity of Louisinana. Prior to coming to Yale, she worked on better understanding mechanisms underlying macrocephaly in patients with 16p11.2 deletion at Stanford. April is interested in ASD and neural mechanisms of social behavior. She is rotating in the lab of AZA Allsop in Psychiatry and co-mentored by Steve. She is also in a Medical Research Scholars Program.
