Biography

About Claire Jansson-Knodell, MD

Dr. Jansson-Knodell is a gastroenterologist and physician-scientist. Her research and clinic focus is celiac disease: an immune-mediated disease of the small intestine that develops in genetically susceptible people after eating gluten, a storage protein in wheat, barley, and rye.

Ever since she took an electron microscopy course in college, Dr. Jansson-Knodell has been fascinated by the small intestine. That is where her passion for gastroenterology started and her interest in caring for patients with gastrointestinal issues.

After medical school she completed her residency in internal medicine at Mayo Clinic and her fellowship in gastroenterology at Indiana University where she was Chief Fellow before she was recruited to start her career at Cleveland Clinic.

Seeing her patients improve when they remove gluten from their diet is the most rewarding part of her work. The collaborative spirit among dietitians and gastroenterologists at Cleveland Clinic enables her to provide the best possible care for her patients. She works in the Celiac Disease Program alongside Dr. Rubio-Tapia her longtime mentor, colleague, and friend.She is actively involved in research on celiac disease and its diagnosis. She holds a grant from the AGA (American Gastroenterological Association) that supports this important work. She also has a research award from the International Society for the Study of Celiac Disease.Dr. Jansson-Knodell is the recipient of the Rising Star research award in the GI department, a member of the Alpha Omega Alpha medical honor society, and winner of the Teacher of the Year award in 2023 selected by the GI fellows.

Despite the cloudy weather, she and her family are quite fond of Cleveland, Ohio and happy to call it home.

Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.
