Associate Research Scientist & Postdoctoral Associates

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.

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.

Graduate Students

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. Megha is a Manton Foundation Fellow.
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
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. Olivia is a Gruber Science Fellow, and also a NSF Gradaute Research Fellow.
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)
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. Emily is a Gruber Science Fellow.
