My research focus is on factors that influence food choice and preference, including food insecurity, food preferences, energy balance, disordered eating cognitions, appetite, mood, and anxiety. My primary focus is on avoidant/restrictive food intake disorder, an eating disorder characterized by restrictive eating that isn’t related to weight and shape concerns. Common causes of avoidant/restrictive food intake disorder include selective/neophobic (“picky”) eating, fears of choking, vomiting, or contamination, functional gastrointestinal symptoms, and lack of appetite or reward motivation for eating. In two complimentary lines of research, I study disordered eating behavior and appetitive traits in people with obesity before and after undergoing bariatric (weight loss) surgery, and the impact of food insecurity on disordered eating behavior. In my research, I use experimental designs as well as latent variable, network, and structural equation modeling in large survey datasets collected from college undergraduates, clinical populations, and on the internet.
