Biography
Mark Salem, M.D., is Director of Inflammatory Bowel Disease Services at the Long Beach VA Health System and HS Assistant Clinical Professor of Medicine-Step 4 at the University of California Irvine. Salem completed an Inflammatory Bowel Disease fellowship at Cedars Sinai Medical Center following his gastroenterology fellowship at Baylor College of Medicine. He received his M.D. from the University of Miami Miller School of Medicine.
Salem's clinical and research work focuses on inflammatory bowel disease, with particular attention to therapeutic drug monitoring, disease surveillance, and extra-intestinal manifestations in IBD patients. His research has examined the impact of ethnicity on surgical outcomes in IBD, the prevalence of axial spondyloarthritis among veterans with IBD, and the role of infliximab concentration monitoring in predicting clinical response. He has also contributed to work on chromoendoscopy for dysplasia surveillance and the role of histology in determining disease activity and treatment decisions.
Salem has presented his research at national conferences including Digestive Disease Week and the Crohn's and Colitis Congress. He is a member of the International Bowel Ultrasound Group and the Crohn's and Colitis Foundation of America. Salem is board certified in both gastroenterology and internal medicine and is fluent in Spanish with medical proficiency.
