In 1993, their trainees Xiaodong Wang and Michael Briggs purified the Sterol regulatory element binding proteins (SREBPs). Since 1993, Drs. Brown, Goldstein, and their colleagues have described the unexpectedly complex machinery by which cells maintain the necessary levels of fats and cholesterol in the face of varying environmental circumstances. Dr. Brown holds The W. A. (Monty) Moncrief Distinguished Chair in Cholesterol and Arteriosclerosis Research; is a Regental Professor of the University of Texas; holds the Paul J. Thomas Chair in Medicine; and is a member of the Board of Scientific Directors at The Scripps Research Institute. Frequently mentioned as a candidate for nationally-prominent positions in scientific administration, Dr. Brown, like his colleague Joseph L. Goldstein, elects to continue hands-on involvement with research, leading a research team that typically includes a dozen doctoral and postdoctoral trainees. He and his colleague are among the most highly cited Scientists in the world.
