    John B. Harley, MD, PhD Director, Center for Autoimmune Genomics and Etiology (CAGE)

    is a rheumatologist and biochemist with special clinical and research interests in the genetic etiology of inflammatory diseases. His experimental focus is the many genetic effects and environmental causes of systemic lupus erythematosus (SLE) and related inflammatory diseases. Through this work, nearly 50 genes are known and Epstein Barr virus has been identified to trigger the systemic autoimmunity of lupus. Dr. Harley also builds infrastructure with which to do high throughput genotyping, expression analysis, and epigenetics, which he makes available to his colleagues from around the world. In recent experiments, Dr. Harley organized the logistics of managing >18,000 subjects at >30,000 genetic markers, 3200 subjects at 1.2 million markers, and 10,000 subjects at 196,000 markers. Dr. Harley is committed to all of the steps between association detection through replication and toward identifying the possible functional genetic variants and to pursuing their biology.

    Andrew B. Herr, PhD

    studies protein-protein interactions involved in immune receptor signaling and bacterial pathogenesis. His lab uses X-ray crystallography to solve the atomic structures of proteins along with techniques of biophysical chemistry to understand their interactions in solution. The goal is to understand the molecular basis for autoimmune responses and recurrent bacterial infections, and to develop new therapeutic applications.
