Research is a major priority of the Division of Rheumatology at WashU Medicine. Our laboratories are working to advance fundamental knowledge of human biology and disease, and our clinicians are conducting numerous clinical trials and epidemiological studies.

Ongoing basic and translational science efforts includes studies of complement, natural killer and other innate lymphoid cells, T-cell biology and mucosal immunology, chikungunya viral arthritis, lupus, innate and adaptive immunity, nanotherapies for rheumatoid arthritis, and human genetics. Clinical research efforts include clincial trials and epidemiological studies of rheumatoid arthritis and lupus.
