About

Biography

I am an assistant professor in Behavioral Medicine and Clinical Psychology at Cincinnati Children's within the University of Cincinnati College of Medicine, Department of Pediatrics. Currently, I am a clinical psychologist within the multi-disciplinary eating disorders team. I specialize in the assessment and evidence-based treatment of eating disorders, including family-based therapy (FBT) for anorexia nervosa. I am also trained in DBT and have recently piloted a DBT skills group. My research interests include personality traits, self-harm, and eating disorders, the treatment of eating disorders within the context of chronic illness (e.g., type 1 diabetes), eating disorders within the transgender population, and evaluating treatment interventions to improve outcomes in adolescents with eating disorders.
