My research is broadly focused on identifying biopsychosocial processes (e.g., reward, emotion regulation and reactivity, weight suppression) underlying the development and maintenance of eating disorders and on identifying factors associated with the high risk for suicide in this population. My research has integrated clinical, behavioral, and biological theories with the aim to develop more comprehensive etiologic models that can inform novel interventions for these complex and deadly illnesses.
Some overarching questions that I aim to address with my research are:
- What makes some individuals (but not others) vulnerable to develop eating disorder psychopathology in response to dieting or psychosocial risks?
a. How do biopsychosocial processes interact to increase risk and maintenance of eating disorders?
b. What adolescent-specific factors contribute to risk during this vulnerable period of eating disorder
- How do weight-related factors (e.g., significant weight loss) and feeding or stress-related hormones influence vulnerability to over- (or under-) eating?
- Why are individuals with eating disorders at increased risk for non-suicidal self-injury and suicidal thoughts and behaviors?
