Dr. Keith Alexander Sharkey is a Professor in the Department of Physiology and Pharmacology at the Cumming School of Medicine, University of Calgary. He is also a Full Member of both the Hotchkiss Brain Institute and The Calvin, Phoebe and Joan Snyder Institute for Chronic Diseases. Dr. Sharkey has been at the University of Calgary since his appointment as Assistant Professor in 1990, dedicating his career to understanding the neural control of the gastrointestinal tract. From 2005-2021, he held the Crohn's and Colitis Canada Chair in Inflammatory Bowel Disease Research, demonstrating his longstanding commitment to advancing knowledge in gastrointestinal sciences. Dr. Sharkey's educational journey began with a BSc (Hons) in Nutrition from the University of London in 1981, followed by a PhD in Physiology from the University of Liverpool in 1985. After completing postdoctoral training in Hungary, the UK, and Canada, he joined the University of Calgary faculty in 1990, where he has remained throughout his distinguished academic career. Dr. Sharkey's research program centers on understanding the physiology and pathophysiology of the neural control of the gastrointestinal tract and brain-gut interactions in health and disease. His laboratory investigates two main areas: the role of the endocannabinoid system in regulating GI motility and intestinal barrier function, and the physiology of the enteric nervous system in controlling motility and barrier function. His work employs state-of-the-art approaches including live cell imaging and molecular genetics. Recent publications show his expanding interest in connections between gut function and neurodegenerative conditions like ALS, with multiple 2024-2025 papers examining sexual dimorphism in disease processes and gut-brain axis mechanisms. Fellow, Royal Society of Canada (2024) Cumming School of Medicine's van de Sande Distinguished Achievement Award for Mentorship (2021) Distinguished Research Award, American Physiological Society (2021) Finkelstein Award for Excellence, Crohn's and Colitis Canada (2016) Fellow, Canadian Academy of Health Sciences (2015) Fellow, Canadian Association of Gastroenterology (2015) Killam Annual Professor Award, University of Calgary (2013) Dr. Sharkey has mentored numerous students throughout his career, as evidenced by his 2021 Mentorship Award. His research is supported by significant funding, including a CIHR Foundation grant exploring how enteric nerves and glia maintain intestinal homeostasis. He has also participated in university strategic initiatives focused on Brain and Mental Health (2015-2021) and Infections, Inflammations and Chronic Diseases (2015-2021), demonstrating his interdisciplinary approach. The Sharkey Lab provides a safe, inclusive, and diverse research environment that encourages open scientific exchange from diverse viewpoints. His laboratory is actively engaged in multiple collaborative projects, including investigations with UBC Okanagan on diet and probiotics targeting the gut-brain metabolic interactome, and with University of Calgary colleagues studying gut microbiota's role in ALS. Dr. Sharkey continues to advance our understanding of neural mechanisms controlling gastrointestinal function with upcoming courses scheduled for Fall 2024 and Winter 2025.
