Jonathan G. Braun, MD, PhD

Jonathan Braun, MD, PhD, is a physician-researcher devoted to the roles of the immune system in resistance and susceptibility to inflammatory bowel disease and cancer. His recent national service includes chair of the National Scientific Advisory Committee of the Crohn's and Colitis Foundation; chair of the Scientific Board, Milieu Interieur, Institute Pasteur; president of the Clinical Immunology Society, and co-founder and president of the Federation of Clinical Immunology Societies, a leading international organization for translational immunology. Dr. Braun's research centers on the mechanisms of microbial-immune commensalism in the intestine and the integration of multi’omic and genetic analysis to advance the diagnosis and treatment of inflammatory bowel disease. The scope of this work includes functional immune assessment, tissue proteomics, genome-wide genetics, and microbiome metagenomics and metabolomics) and participation in the NIDDK IBD Genetics Consortium, NIH HMP2, and as PI of the CCFA Microbiome Consortium. His group is also devoted to new strategies in functional immune assessment, including gene targeting and positron-emission tomography for real-time imaging of immune-mediated inflammation. He has published more than 170 primary research studies, 14 issued patents, and co-founded three biotechnology companies.

Many of the physicians who have medical staff privileges to practice medicine at Cedars-Sinai Medical Center are independent physicians, and not employees or agents of the hospital. These independent physicians bill separately for their services. You should contact your physician to determine their status and billing practices.
