Emily L. Newman, PhD

Assistant Professor in Neuroscience

Ghahreman Khodadad Professorship in Neuroscience

Director, Social Neuroethology Laboratory

Director, The Ghahreman Khodadad Center

Emily received her BSc in Psychology from Tufts University in 2010 and returned to Tufts for graduate training, earning her MSc in Experimental Psychology in 2016 and her PhD in 2020 under the mentorship of Dr. Klaus A. Miczek, PhD. During this time, she became increasingly interested in how neural circuits generate the internal emotional states that shape behavior. She then completed her postdoctoral training in neuroscience at McLean Hospital and Harvard Medical School under Dr. Kerry J. Ressler, MD, PhD, where she studied the neural mechanisms underlying trauma-related behavioral changes and later served as an Instructor in Psychiatry. In 2025, Emily returned to Tufts as an Assistant Professor of Neuroscience at the Tufts University School of Medicine and is a faculty member in the Neuroscience Program at the Tufts Graduate School of Biomedical Sciences. She also serves as Director of The Ghahreman Khodadad Center for the Study of Excessive Pathological Selfishness. 

Emily’s research is driven by a long-standing interest in understanding why social interactions can shift so dramatically—from adaptive forms of aggression, cooperation, and affiliation to social isolation, maladaptive conflict, and violence. Her work focuses on the neurobiological substrates that underlie social behavioral states and how trauma and social experience reshape these processes. By studying how aggressive behavior escalates and how the brain transitions between emotional states, she aims to better understand the biological mechanisms that contribute to cycles of violence and trauma-related psychiatric disorders.

Yingchu He

Doctoral Candidate, Neuroscience PhD Program

Tufts University Graduate School of Biomedical Sciences

Yingchu received her BA in Neuroscience from Boston University, where she conducted research investigating how chronic alcohol exposure alters activation of norepinephrine neurons under the mentorship of Dr. Valentina Sabino. Following graduation, she joined the Maguire Lab at Tufts University as a research technician, where she studied how chronic stress alters neural circuit function to drive behavioral changes. As a PhD student in the Newman Lab at Tufts, Yingchu will study the neural mechanisms underlying inter-brain correlations that emerge during social interactions, and how stress disrupts neural circuits and contributes to maladaptive social behaviors and emotional states.

Jaya Kohol

Research Technician

Jaya graduated from Boston University in 2025 with a degree in Neuroscience. During her time as an undergraduate she worked in the Holly Lab at Rutgers University to study adolescent mouse social isolation behavior. Through her courses and lab work, Jaya has developed an interest in neuropharmacology and rodent behavior and hopes to pursue a PhD in the near future. In the Newman Lab, Jaya is excited to explore how aggression is encoded in the brain as an emotional state and to utilize chemogenetic and optogenetic interventions as methods to understand how traumatic experiences influence and shape behavior. While outside of the lab, Jaya enjoys drawing, reading very long books, running, going to lots of concerts, and listening to alternative music.


Griffen Collins

Undergraduate Researcher, Tufts University

Griffen is an undergraduate at Tufts double-majoring in biopsychology and music. He is thrilled to be investigating the neurocircuitry of social behavior in the Newman Lab. Outside of neuroscience, Griffen loves composing music, singing, playing guitar, swimming, and hiking.
