Jeff Browning

As senior director of immunobiology research at Boston-based Biogen Idec, Browning has presided over the development of several new pharmaceutical drugs. One success story gives him particular satisfaction. Earlier in his career, Browning co-discovered the surface form of lymphotoxin, an important signaling chemical in the human body. The discovery led to the development of Baminercept, an early-stage drug designed to treat rheumatoid arthritis. Biogen is currently ushering this drug through human clinical trials, and scientists there are optimistic it will work to treat other autoimmune diseases as well.
