Ovadia Lev is a professor of chemistry at the Casali Center for Applied Chemistry, the Institute of Chemistry and head of Environmental Chemistry Laboratory of the Hebrew University of Jerusalem. His research focuses on water and wastewater treatment, development of advanced materials for environmental and green chemistry and the analytical chemistry and electrochemistry of trace organic contaminants.

Prof. Lev has contributed to the development of the fields of sol-gel electrochemistry and hydrogen peroxide sol-gel chemistry (including fundamental aspects and applications for lithium and sodium ion batteries), scanning electrochemical mass spectrometry (SCM) and scanning electrochemical microscopy (SECM). Professor Lev has been instrumental in providing science-based regulations, such as the Guidance manual for ozone disinfection in the USA, tools for quantification of leakage from Soil Aquifer Treatment systems to nearby drinking water wells, and quantification of wastewater leakage to water sources by quantification of emerging organic contaminants (micropollutants).


Prof. Lev is recipient of the Fulbright postdoctoral fellowship, the Barnard scholarship awarded by the AAAS and the USEPA, the Key Innovations Award awarded by the Hebrew University and he is Fellow of the International Society of Electrochemistry, the Rita Levi-Montalcini Award for scientific collaboration between Israel and Italy.

The group is participating in a collaborative project in Singapore, holds a laboratory in the CREATE campus in Singapore and some of its members are stationed in Singapore.
