Ricardo De Leon is the laboratory manager of the microbiology unit in the Water Quality Section of the Metropolitan Water District of Southern California in La Verne, California. His current activities and research include the development and implementation of new technology for the detection of infectious Cryptosporidium and other pathogens in water; disinfection of enteric organisms by oxidation and UV light; use of bacterial spores as surrogates for treatment process evaluation; impact of body contact recreation on water quality; and methods development for emerging waterborne pathogens. Dr. De Leon is a member of the Drinking Water Committee of EPA’s Science Advisory Board. He received a B.S. and Ph.D. in microbiology from the University of Arizona.
Daniel Y.C. Fung is professor of animal sciences and industry and professor of food science at Kansas State University. His current research focuses on rapid methods and automation in microbiology related to food, environmental, industrial and medical specimens and microbiology of food processing. Dr. Fung’s research interests include the rapid detection of harmful and beneficial microorganisms in food and the environment and the control of pathogenic organisms by physical and chemical methods, and fermentation procedures. He is the editor of the Journal on Rapid Methods. Dr. Fung has been elected a fellow of the American Academy of Microbiology, Institute for Food Technologists, International Academy of Food Science and Technology, and Institute of Food Science and Technology (U.K.). Dr. Fung received his B.A. in biological sciences from International Christian University in Tokyo, Japan, M.S. in Public Health from the University of North Carolina, and Ph.D. in food technology/food microbiology from Iowa State University.
Charles N. Haas is the Betz Chair Professor of Environmental Engineering at Drexel University. He was formerly a professor and acting chair in the Department of Environmental Engineering at the Illinois Institute of Technology. Dr. Haas’ areas of research involve microbial and chemical risk assessment, hazardous waste processing, industrial wastewater treatment, waste recovery, and water and wastewater disinfection processes. He is a member of the Water Science and Technology Board, a fellow of the American Academy of Microbiology, a councilor of the Society for Risk Analysis, and a director of the Association of Environmental Engineering and Science Professors. Dr. Haas has served on several NRC committees, most recently including the Committee on Toxicants and Pathogens in Biosolids Applied to Land, and NRC’s Panel on Water System Security Research for its Review of EPA Homeland Security Efforts. He received a B.S. in biology and an M.S. in environmental engineering from the Illinois Institute of Technology and a Ph.D. in environmental engineering from the University of Illinois.
