James D. Katz, M.D., is a Senior Research Physician and the director of the Rheumatology Fellowship and Training Branch. He serves as the principal investigator for several arthritis protocols. In this capacity, he is able to support the teaching mission of NIAMS toward helping to create the next generation of physician-scientists.

The adult Rheumatology Fellowship program provides training leading to ACGME-certification in Rheumatology while allowing Fellows to participate in full-scale research projects under the supervision of NIAMS or affiliated faculty during the upper years of their Fellowships.

Research Statement

The NIAMS Community Health Clinic was established in 2001 to fulfill a dual mission for the clinical program: (1) to broaden the clinical exposure of NIAMS Rheumatology Fellows, and (2) to provide an additional site for recruitment of patients from under-represented groups with rheumatic diseases to NIAMS clinical studies.
