Daniel Talmasov is a physician-neuroscientist with dual training in neurology and psychiatry. Dr. Talmasov’s research applies core neurologic principles to understand how distinct and stereotyped clusters of psychiatric symptoms emerge from the interactions of specific disease processes and neuroanatomic networks subserving human behavior. Dr. Talmasov’s work in the ADAPT lab aims to clarify how clinical heterogeneity in the psychiatric manifestations of Alzheimer’s disease relates to the relative burdens of proteinopathy, atrophy, and inflammation in the brains of affected individuals.

Dr. Talmasov trained in psychiatry at the Brigham and Women’s Hospital / Harvard Medical School program, and in Neurology at the NYU Grossman School of Medicine. Dr. Talmasov is presently a clinical fellow in Columbia’s Behavioral Neurology and Neuropsychiatry fellowship program and concurrently a T32 research fellow in late-life neuropsychiatric disorders.
