Postdoctoral Associate
Ph.D. (Institute of Neuroscience, Chinese Academy of Sciences)
Guangyao received his PhD in Neurosciences working with Liping Wang, where he studied the computational and frontoparietal circuit mechanisms of causal inference in multisensory perception. Guangyao is interested in studying the neural mechanisms underlying social decision-making.

Weikang Shi, PhD   [google scholar]
Postdoctoral Fellow
Ph.D. (Washington University in St. Louis)
Weikang received his PhD in Neurosciences working with Camillo Padoa-Schioppa, where he studied the neurophysiological mechanisms underlying value guided decision-making in the orbitofrontal cortex. Weikang is interested in studying the neural mechanisms underlying complex social interaction. Weikang is a Wu Tsai Institute postdoctoral fellow co-mentored by Chang, Nandy, and Jadi.

Software Engineer

Nicholas Fagan

Graduate Students

Sylvia Blackmore  
Graduate Student

Sylvia received her BA degree in Liberal Arts from St. John’s College and Psychology from UC Berkeley. She also received her Masters of Science degree from University College London in Dual Brain and Mind Sciences. She has research experience in computational modeling and neuronal data analyses. Sylvia is a Wu Tsai Institute Graduate Student Fellow.

Dan Calbick 
INP Rotating Student

Dan Calbick received his B.S. in Neuroscience from Yale in 2020. During undergrad, he did research in the McCormick and Lim labs on vocal-motor coordination and spinal cerebellar ataxia, respectively. Post-graduation, he joined Gregory McCarthy’s lab, studying object recognition in the ventral-visual stream. Currently, he is rotating in the Chang Lab, exploring how oxytocin in the amygdala affects the neural dynamics involved in social behavior. Broadly, he is interested in dynamic networks’ role in encoding complex temporal data into abstract states, important for maintaining stable yet flexible behavior.

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.

Shadé Eleazer 
INP Rotating Graduate Student
Shadé received her BS degree in Behavioral Neuroscience and Biomedical Sciences from Marymount Manhattan College. During undergrad, she had numerous research opportunities in the New York City area including at Mount Sinai Hospital, Weil Cornell Medicine, and at Rockefeller University. Before joining Yale, she was a Simons Collaboration on the Global Brain Undergraduate Research Fellow in Vanessa Ruta’s lab at Rockefeller. Shadé is excited to learn more about the neural mechanisms that influence social interactions and social behaviors while rotating in the lab. Shadé is also a part of the inaugural cohort Wu Tsai Institute graduate fellows.
