Dr. C. Alix Timko is an Assistant Professor of Psychology in Psychiatry in the Department of Psychiatry in the Perelman School of Medicine at the University of Pennsylvania. She is also a clinician in the Eating Disorder Assessment and Treatment Program in the Department of Child and adolescent psychiatry and Behavioral Sciences at Children’s Hospital of Philadelphia.

Dr. Timko’s prior work has focused understanding eating behavior in young adults, the use of acceptance-based behavioral therapy (in particular Acceptance and Commitment Therapy) in treating eating disorders, and the presentation of disordered eating in boys.

Currently, she is a Building Interdisciplinary Research Careers in Women’s Health (BIRCWH) Scholar, and is supported by a K12 award (PI: Maria A. Oquendo, MD, PhD).  The purpose of the BIRCWH is to extend her expertise into the area of neuroscience, specifically in behavioral neuroendocrinology and the use of neuroimaging. Her current work focuses in the area of neurocognition, reward circuitry, and what role they play (separately and together) in the development and maintenance of anorexia nervosa. She is actively examining sex differences in social reward in adolescents with anorexia nervosa as well as the role of role of sex hormones in the development and/or maintenance of anorexia. Her work includes examining how malnutrition during this sensitive period impacts brain development. The end goal is to identify biomarkers of a longer course of illness and use this information to develop or refine treatments for adolescents in order to improve outcome and reduce relapse.

Her most recent research has examined the use of Cognitive Remediation Therapy with adolescents in hospital for medical stabilization of their anorexia. The purpose of this was to determine if using CRT on a hospital unit was feasible. The study also examined whether or not CRT enhanced willingness to engage in treatment post-discharge, improved rate of weight gain, and reduced symptom accommodation.
