Russell Cohen

Russell Cohen is a Professor in the Department of Medicine-Gastroenterology at the University of Chicago, where he has established himself as a leading expert in inflammatory bowel disease (IBD) with a focus on Crohn's disease and ulcerative colitis. His extensive research portfolio spans clinical investigation, therapeutic development, and patient care optimization.

Dr. Cohen's primary research interests include:

• Inflammatory Bowel Disease pathophysiology and management
• Biologic therapies and biosimilars for IBD
• Treatment optimization for Crohn's disease and ulcerative colitis
• Real-world effectiveness of novel IBD therapies
• J-pouch surgery outcomes and complications
• Pharmacoeconomics of IBD treatment
• Pregnancy outcomes in IBD patients

His recent publications (2023-2025) demonstrate continued leadership in evaluating newer biologic agents including mirikizumab and risankizumab, biosimilar medications, and the impact of healthcare system factors like prior authorization on treatment outcomes. His work on J-pouch phenotypes has refined postoperative management strategies, while research on proximal colon inflammation patterns has informed cancer surveillance approaches in high-risk patients.

Dr. Cohen has collaborated extensively with colleagues at the University of Chicago and other institutions, contributing to numerous clinical studies that have shaped current IBD management practices. His work frequently appears in high-impact gastroenterology journals including Gastroenterology, Clinical Gastroenterology and Hepatology, and Inflammatory Bowel Diseases.
