The research of Kathrin Michelsen, PhD, focuses on the role of innate and adaptive immunity in the development of intestinal inflammation. Animal models are used to elucidate the molecular mechanism of dysregulated immune responses that lead to chronic inflammation of the mucosa. The mouse models of intestinal inflammation are used as pre-clinical models to conduct laboratory studies that will identify molecules for eventual therapeutic intervention.

Many of the physicians who have medical staff privileges to practice medicine at Cedars-Sinai Medical Center are independent physicians, and not employees or agents of the hospital. These independent physicians bill separately for their services. You should contact your physician to determine their status and billing practices.
