James Englehardt

Civil, Architectural and Environmental Engineering
University of Miami
United States of America


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 the 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 serves on the US Environmental Protection Agency (EPA) Science Advisory Board, Drinking Water Advisory Committee, and as Associate Editor for ASCE-ASME Risk and Uncertainty in Engineering Systems, Part A Civil Engineering, and ASCE-ASME Risk and Uncertainty in Engineering Systems, Part B Mechanical Engineering. Awards include the Johnson A. Edosomwan Outstanding Publication Award, 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.

Research Interest

Dr. Englehardt currently directs the Water Quality Engineering Laboratory. Developments include the energy-positive net-zero water treatment system for management of municipal water and wastewater; and machine learning/evidence fusion technology for sensor-based detection of health risk in drinking water in near-real time, both under support of the National Science Foundation and the U.S. Environmental Protection Agency (EPA). Discoveries in the field of risk analysis include an explanation of 1/f noise (the power law Fourier transform signature of complex system-generated time series of outcome magnitudes); derivation of discrete and continuous probability distributions for illness severities, microbial concentrations in water over time, and other complex system outcome sizes; and derivation of a general multivariate dose-response function for mixtures of chemical toxicants in water and other media.
