Eating disorders and suicide often co-occur, have similar risk factors, and can serve similar functions. Beyond the eating disorder - suicide overlap, I also conduct projects related to comorbidity, in general, and dimensional classification.

Example questions I tackle within this research area are:

  1. Why do eating disorders and suicide co-occur at such high rates?
  2. What factors influence both eating disorders and suicide?
  3. Do psychiatric comorbidities impact eating disorder treatment outcomes?

Example papers within this content area include, but are not limited to:
