Elimenech’s research focuses on the water-energy nexus, emphasizing membrane-based processes for energy-efficient desalination and wastewater reuse, advanced materials for next-generation environmental separation, and the environmental applications of nanomaterials.

Center for Water Research in Houston, Texas

At Rice University, Elimenech is now Professor of Civil and Environmental Engineering, with a joint appointment in the Department of Chemical and Biomolecular Engineering.
“Rice is recognized internationally as a center for water research. You have the Rice WaTER Institute, NEWT and researchers who are known around the world. I am looking forward to working with them,” said Elimelech in October 2024.

“Among his numerous scientific contributions, Dr. Elimelech pioneered the use of membrane-based technologies for desalination and brine management, including forward osmosis, high-pressure reverse osmosis, and low-salt-rejection reverse osmosis,” said Pedro Alvarez, the George R. Brown Professor of CEE and director of the NSF Engineering Research Center on Nanotechnology-Enabled Water Treatment (NEWT) since its founding in 2015.
“He is renowned for his outstanding mentorship,” Alvarez continued,” having served as adviser to some more than 50 Ph.D. students and 50 postdoctoral fellows, 70 of whom are now professors.”

Most cited environmental and water expert in the world

Elimenech has authored over 560 peer-reviewed journal publications and is one of the most cited scholars in his field, with an h-index¹ of 207 and over 160, citations, as of 30 January 2025.
According to Alvarez, this makes him the environmental engineer or water scientist with the highest bibliographic impact in the world.

From Israel to USA

Born in Israel to Moroccan immigrant parents, Elimenech overcame early life challenges to achieve academic excellence. He earned his Bachelor and Master of Science degrees from the Hebrew University of Jerusalem in 1983 and 1985, respectively, followed by a PhD in environmental engineering from Johns Hopkins University in 1989.
Elimelech began his academic career at the University of California, Los Angeles (UCLA), where he progressed from assistant to full professor. In 1998, he joined Yale University, founding its Environmental Engineering program and later being appointed as the Sterling Professor of Chemical and Environmental Engineering, the highest academic rank at Yale.

¹ The h-index, proposed by Hirsch in 2005, is a measure to calculate the output of a researcher. With an h-index of 10, 10 publications by an author are cited at least 10 times.
