I am a clinical gastroenterologist with a research focus on the epidemiology of celiac disease, with a specific focus on risk factors, quality, and outcomes. During my training in preventive oncology and population sciences in an NCI-funded fellowship under the mentorship of Alfred I. Neugut, I performed studies in bowel preparation prior to colonoscopy and adherence to biopsy standards in the diagnosis of celiac disease. I have used the analytical skills gained from that fellowship and from the master’s degree in Patient-Oriented Research to study these conditions using large data sets from the US and Sweden. My research activities include the conduct of epidemiologic analyses including cohort and case-control studies and clinical trials.

Research Interests

  • Epidemiology and outcomes in celiac disease
  • Field of quality in endoscopy
