Dr. James Englehardt, P.E., is Professor of Environmental Engineering at the University of Miami, appointed 1992.  Before receiving his Ph.D. from the University of California, Davis, Dr. Englehardt led filtration research projects for Johns Manville Corporation (1983-1987), and supervised water treatment laboratory development and field service for the Western Filter Company (now GE Water) (1978-1980).  He currently directs the Water Quality Engineering Laboratory.  Developments include net-zero water treatment, that is the first energy-positive treatment system for management of municipal water and wastewater; a patented low-energy chemical-free electrochemical process for recovering nutrients as fertilizer from sewage; the first inferential models for tracking of relatively slow-moving pollutant masses; and the first machine learning/evidence fusion algorithms for sensor-based detection of health risk in drinking water in near-real time, under support of the National Science Foundation (NSF), the U.S. Environmental Protection Agency (EPA), the Gulf of Mexico Research Initiative (GoMRI), and the Electric Power Research Institute (EPRI). Discoveries in the field of risk analysis include the first general explanation of 1/f noise (a signature of complex system data); derivation of probability distributions for complex system outcomes including illness severities and microbial concentrations; and derivation of the first general dose-response function for mixtures of chemical toxicants.

Dr. Englehardt serves on the EPA Science Advisory Board (SAB), Drinking Water Advisory Committee, and as Associate Editor for PLoS ONE, and for ASCE-ASME Risk and Uncertainty in Engineering Systems, Parts A Civil Engineering and ASCE-ASME Risk and Uncertainty in Engineering Systems, Part B Mechanical Engineering B.  Awards include the WaterReuse Association 2018 Award for Excellence in Transformation Innovation, two Johnson A. Edosomwan Outstanding Publication Awards, University of Miami; the Science Advisor’s Award, EPA National Center for Environmental Assessment; the Robert C. Barnard Environmental Science & Engineering Award for Advances in Risk Assessment, American Association for the Advancement of Science and EPA; and two University of Miami Eliahu I. Jury Awards for excellence in research.
