I obtained my Ph.D. in Chemistry from University College London (UCL, 1981), UK and BSc. from Jordan University.  My early research at UCL London, was on photochemistry before joining (1983) the National Research Council (NRC), Ottawa, to work on nanosecond laser photochemistry where I developed technologies to destroy PCBs and dioxins.  In 1987, I joined the Biotechnology Research Institute in Montreal to create the Environmental Chemistry Department.  In 2005 I became a Principal Research Scientist and stayed 33 years before joining academic institutions.  My main research interests are focused on Environmental sciences and engineering and Green chemistry for green technologies and green products. I serve/served as professerur associé at Sherbrook University, Ecole Polytechnique, and McGill University.  I collaborated and received funding from several agencies (NSERC, DND, Shell, Imperial Oil, Exxon, Shaw Environment, SNC Lavalin, US PNNL, ONR-US Navy, and US DOD and DOE (SERDP). My awards include 2NRC outstanding achievement awards, Golden Medal-Queen Elizabeth; US SERDP- project of the year award; 4Institute DG awards, Amer Chem Soc Excellence in Review Award; 2TTCP (Canada, US, Australia & New Zeeland) awards, Science Alumni Jordan University award.  I hold 7 patents, 300+ publications and co-authored a book on ecotoxicology. My google scholar citation is 10,673 and h-index: 59
