About Us

The eating disorders workgroup has been a part of the PGC since 2013. During that time, our membership has grown to include investigators from over 20 countries spanning North America, Europe, Asia, and Australasia. Our group focuses on the study of anorexia nervosa, bulimia nervosa, and binge-eating disorder.

Profs. Cynthia Bulik (University of North Carolina at Chapel Hill and Karolinska Institutet, Stockholm, Sweden) and Gerome Breen (King’s College London, UK) chair our group. Our interdisciplinary membership includes graduate and postdoctoral trainees from a range of disciplines as well as distinguished faculty in psychiatry, psychology, biostatistics, genetics, and related fields. We are currently working toward uniting researchers and clinicians from around the world to create the largest collection of DNA from individuals with eating disorders in the world. Our current goals are to rapidly increase sample size for our anorexia nervosa studies and to expand our scope to complete GWAS for bulimia nervosa, binge-eating disorder, and avoidant and restrictive food intake disorder (ARFID).

Members of the workgroup stay connected through regular conference calls on the first Thursday of every month and via our workgroup listserve. Please contact Andri Savva if interested in learning more about the conference calls. If you are a member of the eating disorders workgroup and have questions about a specific analysis or if you are interested in joining an ongoing approved secondary analysis project, please contact the investigator leading that project.

We are an open and welcoming group. If you have samples from patients with eating disorders and would like to join the group and have your samples genotyped, please contact us. If you are interested in hearing more, please contact either Cynthia Bulik or Gerome Breen.
