Dr. Kriegel is an Assistant Professor of Immunobiology and of Medicine (Rheumatology) at Yale School of Medicine. In 2001, he received his MD/PhD equivalent at the Friedrich-Alexander University of Erlangen, Germany, followed by the German Medical Licensure in 2002. From 2003 to 2006, he performed postdoctoral training in immunology at Yale with Dr. Richard Flavell before completing a medicine residency and rheumatology fellowship at Harvard (Beth Israel Deaconess Medical Center and Brigham & Women’s Hospital). During this time, he performed additional postdoctoral research at Harvard Medical School with Drs. Diane Mathis and Christophe Benoist. Dr. Kriegel returned to Yale in 2012 as a tenure-track faculty member in the Department of Immunobiology. He is also a board-certified rheumatologist at Yale-New Haven Hospital and maintains a specialty clinic for antiphospholipid syndrome. His NIH-funded laboratory explores host-microbiota interactions in immune diseases by combining human microbiome studies with mechanistic work, which includes utilization of gnotobiotic models. He was an Emmy-Noether Scholar of the German Research Foundation, an Arthritis National Research Foundation Scholar, an awardee of the Lupus Research Institute, and the Arthritis Foundation. He serves as an Advisory Editor for Arthritis & Rheumatology and is a member of the American Association for the Advancement of Science, the German and American Association of Immunologists, the American College of Rheumatology, and the Society for Mucosal Immunology.

Gut microbe-immune interactions

Cartoon depicting how environmental factors (such as diet) can affect the gut microbiota that in turn modulates immune cell functions. The microbiota effects on adaptive immunity lead to autoimmune and thrombotic complications in lupus and antiphospholipid syndrome.
