Translational research in eating disorders, including biological and psychological factors that contribute to binge eating and purging behaviors; nosology and statistical approaches to classification; longitudinal and epidemiological studies of psychological, social and cultural factors that influence eating disorders and body image.
Current projects include an examination of psychological and biological factors that may distinguish individuals with purging disorder (characterized by recurrent purging following normal or small amounts of food in individuals who are not underweight) from individuals with bulimia nervosa and individuals without eating disorders. We are also developing papers from a 4th assessment wave of a large epidemiological and longitudinal study of bulimic syndromes in which we have sampled college cohorts in 1982, 1992, 2002, and now 2012 with successive waves of 10-, 20-, and now 30-year follow-up assessments of established cohorts. Finally, we have a large grant examining the biological consequences of weight suppression and how these may explain the association between weight suppression and illness maintenance in bulimic syndromes.
