  • Instructor in Psychiatry


Alaptagin Khan, MBBS, FRSPH,is a research associate at McLean Hospital and an instructor in psychiatry at Harvard Medical School. After graduating from medical school, Dr. Khan took the opportunity to work with the Red Cross and UNICEF in conflict zones where he developed an interest in PTSD and the neurobiology of traumatic stress.

At McLean Hospital, Dr. Khan’s work primarily revolves around developmental trauma, depression, and complex PTSD. In particular, his research focuses on identifying developmental sensitive periods where exposure to childhood adversity has greatest impact on risk for developing major depression, suicidal ideation, PTSD, personality disorders, and substance abuse. This presence of sensitive exposure periods may lead to a more precise clinical and neurobiological understanding of susceptibility and resilience and can help define times when interventions can have the most potent effects.
