Dr. Tonya Kaltenbach, Key Advisor
Dr. Kaltenbach is Co-‐Director of Advanced GI Endoscopy, Inc, and an Associate Professor of Clinical Medicine at the University of California San Francisco. She has served on the US Multi-‐Society Task Force on Colorectal Cancer and on the National Comprehensive Cancer Network (NCCN) Colorectal Cancer Screening Panel, and is active in GI societies as a Fellow of the American Society for Gastrointestinal Endoscopy and American College of Gastroenterology.She completed internal medicine and gastroenterology subspecialty training at Stanford University. During GI fellowship, she matriculated in a clinical research masters program in epidemiology and biostatistics, and then pursued an additional year of training in advanced endoscopic mucosal imaging and therapy and endoscopic ultrasound. Over the years she has also collaborated and directly trained with Japanese experts on endoscopic imaging and removal techniques, including endoscopic submucosal dissection.
Through her work as a thoughtful clinician, researcher and educator, she has published over 125 works, many of them seminal observational studies, randomized trials, guidelines and endoscopy teaching videos relevant to colorectal cancer prevention through the endoscopic detection, diagnosis and removal of polyps, particularly for flat and serrated-‐class lesions. She has co-‐produced numerous endoscopy-‐teaching videos such as Non-‐Polypoid (Flat & Depressed) Colorectal Neoplasm, Chromoendoscopy with Targeted Biopsy to Detect Nonpolypoid Colorectal Neoplasm in Inflammatory Bowel Disease, Image Enhanced Endoscopy and Optical Diagnosis of Colorectal Polyps, seven of which were recognized with the ASGE Audiovisual Award. She was also honored with the 2014 ASGE Distinguished Educator Award.
She played a major role in the recent international efforts to enhance the quality of colonoscopy for the surveillance and management of dysplasia in inflammatory bowel disease patients. These efforts have brought forward a new paradigm that is built on evidence-‐based medicine, including guidelines, videos and atlases. She is currently leading a national initiative to develop a natural language processing algorithm that will measure and report colonoscopy quality across the VAs, and moreover, aims to improve colonoscopy quality through provider feedback and teaching. She continues to serve as faculty at various didactic and hands-‐on courses worldwide.
