Dr. Zeller’s current and primary research focus is the psychosocial adjustment, quality of life, and emerging risks for adolescents with extreme obesity and their psychosocial outcomes when they undergo bariatric surgery. She is the lead behavioral co-investigator and serves on the Steering Committee within the Teen-Longitudinal Assessment of Bariatric Surgery consortium (Teen-LABS), a five-center research consortium developed in cooperation with NIDDK staff (PI:Inge).

Her ongoing R01 Teen-LABS ancillary studies TeenView (R01DK080020) and TeenVIEW3 (R01DA033415) focus on psychosocial risk and protective factors associated with health, quality of life, and developmental outcomes for adolescent bariatric patients as they transition to young adulthood, findings which will have direct impact on defining age-salient care models for this age group.
