    Collapse Overview
    I provide clinical care at Zuckerberg San Francisco General Hospital, where I specialize in caring for patients with inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis. I also see patients with any gastroenterological disease and perform endoscopic procedures, including upper endoscopy and colonoscopy. Additionally, I direct the Gastroenterology eReferral program, reviewing all referrals to the ambulatory GI clinic.

    I pursue educational research, specifically using Cognitive Load Theory to study procedural skills training using colonoscopy as an exemplar setting. I am working on several studies using cognitive load theory in the pursuit of a PhD in Health Professions Education through a joint program between UCSF and Utrecht University, Netherlands. I have experience in quantitative and qualitative methods, as well as in systematic review techniques.

    I am an Element Director for the 1st-year medical student REGulatioN (Renal, Endocrine, Gastroenterology, and Nutrition) course, and I am heavily involved in leadership and administration in the UCSF Bridges Curriculum. I supervise and teach gastroenterology fellows, as well as medical and surgical residents, and medical students, as they rotate through the GI service at San Francisco General Hospital.
