A.              Personal Statement

Early in my academic surgical career, I led a national consensus around medically-appropriate use of surgical therapy for a new and relatively untreated serious health condition:  adolescent severe obesity.  Throughout my professional career, I have dedicated my time to understanding the outcomes of surgery and have shared our findings in the dozens of high-quality manuscripts.  Linking practice to organized clinical research objectives, our team began to critically evaluate surgical interventions and fill gaps in our knowledge base with R03 funding examining beta cell function and insulin resistance in adolescents undergoing gastric bypass beginning in 2005.  However, the major platform for this scholarly work has been U01 funding that was awarded by NIDDK in 2006 to establish the Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) research consortium.  I have served as the PI for the Teen-LABS grant through 3 cycles of funding since 2006With the largest and most comprehensive prospective adolescent bariatric study to date, Teen-LABS investigators have analyzed the baseline phenotype and outcomes of 242 individuals who were exposed to bariatric surgery in adolescence.  The cohort has been carefully characterized, including comorbidity burden, cardiometabolic assessments, diabetes, kidney function, fatty liver disease, musculoskeletal pain and disability, weight related quality of life, depressive symptoms, and micronutrient deficiencies.  In my role as PI of Teen LABS, and surgical director of the Bariatric Center at Children’s Colorado, I will provide scientific leadership for this study and also enthusiastically recruit participants.  

Ongoing projects that I would like to highlight include:

C.              Contributions to Science

1.   Early in my career as a clinical investigator, my publications highlighted the need for an organized and conservative clinical approach to the evaluation and surgical management of adolescents who were developing health problems associated with severe obesity. In addition to providing clinical guidelines, these publications also identified and described clinical challenges and knowledge gaps in the field.

a.   Inge TH, Zeller M, Lawson L, Daniels SR. Critical Appraisal of the Evidence Supporting Bariatric Surgery for Weight Management in Adolescence. Journal of Pediatrics. 2005 Jul;147(1):10-9. PMID: 16027686

  1. Inge TH, Donnelly LF, Vierra M, Cohen A, Daniels SR, Garcia VF. Managing Bariatric Patients In a Childrens Hospital: Radiologic Considerations and Limitations. Journal of Pediatric Surgery, 2005. 40:609-617. PMID: 15852267


  1. By first developing an appropriate clinical framework for patient evaluation and selection for surgery, the next step scientifically was to begin to study this very unique group of young patients who were developing a significant burden of obesity related health problems. In addition, our group was one of the first to begin to examine a wide range of clinical outcomes of surgical treatment at our center.

Reversal of type 2 diabetes mellitus and improvements in cardiovascular risk factors after surgical weight loss in adolescents. Pediatrics. 2009 Jan;123(1):214-22. PMID: 19117885


  1. In an effort to model the long term effects of untreated childhood obesity, we next examined the effect of a history of adolescent obesity on adult health status, testing the hypothesis that adolescent obesity would be associated with greater risks of adverse health later in life. Indeed we found that compared with healthy weight at age 18, class 2 obesity at age 18 independently and significantly increased the risk of a number of comorbid conditions in severely obese adults.
