Hansoo Chang, PhD, is a Postdoctoral Research Fellow in the Dickerson Lab at Massachusetts General Hospital and Harvard Medical School. His research broadly focuses on brain aging, cognition, and neurodegenerative disease, with particular interests in using neuroimaging and noninvasive brain stimulation, including transcranial magnetic stimulation (TMS), to understand and modulate brain networks involved in cognition. He received his PhD in Applied Cognitive and Brain Sciences from Drexel University, where his research used neuroimaging and computational approaches to study individual differences in brain and biological aging. Outside of work, Hansoo enjoys trying new food and playing basketball.
