Menachem Elimelech holds a B.S. in Soil and Water Sciences and an M.S. in Environmental Science and Technology from the Hebrew University in Jerusalem and a Ph.D. in Environmental Engineering from Johns Hopkins University. As his first appointment, Elimelech served as professor and vice chair of the Department of Civil and Environmental Engineering at UCLA. Upon coming to Yale in 1998, he founded Yale’s Environmental Engineering Program, of which he continues to serve as director. Professor Elimelech was elected to the National Academy of Engineering in 2006 and was awarded the Athalie Richardson Irvine Clarke Prize in 2005. His research focuses on problems involving physicochemical and biophysical processes in engineered and natural environmental systems, including: (i) membrane separations for desalination and water quality control, (ii) transport and adhesion of microbial pathogens, (iii) processes involving nanoparticles and biomacromolecules, and (iv) water, sanitation, and public health in developing countries. Professor Elimelech has authored more than 180 refereed journal publications and is a co-author of the book Particle Deposition and Aggregation (1995). He currently serves on the Editorial Advisory Boards of Colloids and Surfaces A, Desalination, Environmental Science & Technology, Environmental Engineering Science, and Separation Science and Technology.
