dation processes. Dr. Walker’s research activities are inherently multidisciplinary, involving researchers from applied and engineering physics, civil and environmental engineering, molecular biology and genetics, microbiology, plant pathology and plant biology. In addition, Dr. Walker is coordinator of the Biomolecular Devices and Analysis Program, the director of the Northeast Sun Grant Initiative, a former member of the National Biomass Research and Development Technical Advisory Committee, and coeditor of Industrial Biotechnology.

Janet Westpheling is a professor in the Department of Genetics at the University of Georgia. She earned her PhD in 1980 from the John Innes Institute in Norwich, England. Her primary research involves the control of gene expression in Streptomyces with emphasis on the study of carbon use and primary metabolism, and the strategies used by bacteria to regulate genes involved in morphogenesis and antibiotic production. Streptomyces is of particular interest because it produces most of the natural-product antibiotics used in human and animal health care. Dr. Westpheling serves on the Journal of Bacteriology Editorial Board and was chair of the Gordon Research Conference on Microbial Stress Response in 1996. She serves as a member of the Scientific Advisory Boards of several biotechnology companies interested in natural-product drug discovery and is a consultant to pharmaceutical and biotechnology companies. Dr. Westpheling participates annually in a course on fermentation technology offered by the Chemical Engineering Department at the Massachusetts Institute of Technology.
