I am interested in the expression of sex in the brain.  My research focuses on a species of clownfish, Amphiprion ocellaris.  Clownfish begin their lives as males, and later in life some will change sex and become female.  Sex change involves reorganization of both the gonads and the brain.  We are using this model to investigate the relationship between brain sex and gonadal sex, and to shed light on deeply conserved aspects of sexual development and differentiation.
