Razi is a postdoctoral fellow in Prof. Elimelech’s research group since February 2017. He received his doctorate from the Department of Civil and Environmental Engineering at the Technion – Israel Institute of Technology. In his doctoral research, he focused on the development of a novel hydrogen-based reactor for groundwater denitrification and enriched his knowledge in biological processes for water and wastewater treatment. His work, based on a simple but tricky concept, was culminated in several papers and a patent.  Razi completed his M.Sc. at the Department of Environmental Engineering, Ben-Gurion University of the Negev, Israel, with his thesis involving optimization of tertiary treatment of municipal wastewater by means of coagulation and ultrafiltration. He obtained his B.Sc. degree from the Department of Biotechnology Engineering, Ben-Gurion University of the Negev, Israel.

In the beginning of his Ph.D. studies, Razi conducted a series of experiments for investigating a novel nanofiltration-reverse osmosis hybrid filtration scheme for the removal of nitrate from groundwater. The new patented process produces low-concentrated brine that can be easily discharged to the sewerage system according to the emerging strict regulations. This work became one of his main motivating factors to choose Prof. Elimelech as a mentor for postdoctoral research. In order to further develop and implement this envisioned filtration method, special nanofiltration membranes must be developed. Razi realized that the knowledge and equipment required for the fabrication of these special membranes can be found in Prof. Elimelech’s lab at Yale University, which specializes in membrane technology research. Moreover, Razi sees membrane technology as a key field in the area of environmental engineering and therefore he is eager to learn more about it.

Outside the lab, Razi is still discovering America and enjoys travelling, playing basketball, watching movies and meeting new people.
