Waliul Khan

Dr. Waliul Khan is a Professor in the Department of Pathology & Molecular Medicine at McMaster University's Faculty of Health Sciences. He leads a research laboratory situated within the Farncombe Family Digestive Health Research Institute, focusing on gastrointestinal health and its complex interplay with intestinal serotonin, microbiota, autophagy, and host defense mechanisms.

His research interests span Gastroenterology, Immunology, Microbiology, and Parasitology, with a specific focus on inflammatory bowel disease (IBD), host-pathogen interactions, and intestinal immune responses. Dr. Khan's work has established critical connections between gut-derived serotonin, immune function, and microbiome composition, revealing novel pathways in intestinal inflammation and host defense.

Analysis of Dr. Khan's recent publications reveals a strong trend toward understanding the role of serotonin signaling in gut health, particularly its impact on immune responses, microbiome composition, and barrier function. His research has expanded into examining how food additives influence gut health, how probiotics like Akkermansia muciniphila modulate inflammation, and how circadian rhythms affect intestinal inflammation.

• Picked up by 109 news outlets for research on food dyes and IBD
• Featured in Nature Communications for work on Allura Red and colitis
• Extensive media coverage for serotonin research
• Highly cited publications with up to 735 Mendeley readers
• Research referenced in multiple Wikipedia pages and patents

Dr. Khan teaches Integrated Systems in Gastrointestinal Health and Disease I (MEDSCI 713) and Clinical Biochemistry (BIOCHEM 3H03) at McMaster University. His laboratory investigates the mechanisms underlying gastrointestinal disorders, with the goal of developing improved diagnostic strategies and therapeutic interventions for conditions like inflammatory bowel disease.
