Research Summary:

Dr. Mitchell’s research focuses on sex and gender differences in mood disorders in adolescence. It encompasses several disciplines, including epidemiology, neuroimaging, and psychosocial treatment, in effort to clearly and broadly characterize sex- and gender-specific similarities and differences among adolescents with mood disorders during this formative period. Two main foci for her work are:

  1. self-harm and suicide-related-behaviour, as sex and gender differences are the rule not the exception; and
  2. bipolar disorder, as the female-to-male prevalence is ~2:1 at no other point in the lifespan.

The overarching goal is to contribute to the development of effective and personalized interventions, at the earliest stages of illness, to reduce the overwhelming burden of mood disorders in adolescents into adulthood.
