Faculty Directory


Dr. John Sidtis’ research has focused on brain-behavior relationships with a special interest in speech, language, and cognition. He was a founding member of the first program in Cognitive Neuroscience, inaugurated at the Cornell University Medical College and Rockefeller University by Michael Gazzaniga and George Miller in 1978. Dr. Sidtis became a licensed neuropsychologist in 1982, which allowed him to gain significant experience with a wide range of neurological and psychiatric populations, providing a valuable foundation for his research. He has been studying brain-behavior relationships in clinical and normal populations for over 40 years, with extensive clinical experience attending at the New York Hospital, Memorial Sloan-Kettering Cancer Center, Burke Rehabilitation Hospital, the Minneapolis VA Hospital, the University of Minnesota Hospital, and since 2001, the Nathan Kline Institute.
