Professional Summary:

My research is focused on improving clinical interventions and subsequent outcomes for individuals with and those at risk for eating disorders and associated health concerns. To this end, I have applied a range of naturalistic assessment and passive sensing strategies to improve understanding of factors contributing to disordered eating in individuals’ real-world environments. For optimal treatment, as important as identifying who is at risk based on trait-level differences, is identifying when and why an individual is at risk, based on state-differences such as variability in environment or mood. My work has pointed to the role of social problems and autonomic dysregulation (i.e., changes in heart rate/heart rate variability in the absence of physical activity), in leading to disordered eating in teens. Another major priority of my research is identifying and targeting systems-level, environmental factors that affect eating and weight disorders, such as food insecurity and weight stigma. I am particularly interested in how inaccurate and negative messages about body weight contribute to the development or maintenance of illness.

My clinical work is focused on applying evidence-based interventions for adolescents and adults with a range of concerns including eating disorders, body image disturbance, anxiety and depression, and more general stressors, including relationship challenges, or life transitions. I employ a range of approaches, predominantly cognitive-behavioral therapy and interpersonal psychotherapy, to help individuals reach collaboratively set goals. I am also trained in family-based therapy (i.e., “The Maudsley Method”), which is considered a first-line treatment for adolescents with anorexia nervosa. In my clinical work, I collaborate with pediatricians, primary care physicians, endocrinologists, nutritionists, and family members to provide coordinated, optimal care to adolescents, adults, and families.

Academically, I mentor and supervise students across levels of training including didactic teaching, clinical supervision, and research mentorship. I serve as a reviewer for the International Journal of Eating Disorders and numerous additional academic journals.
