Aaron joined Saudi Aramco in 2013 and works with the Chemicals R&D Division, at the Research and Development Center. Since joining the Chemicals R&D Division, Aaron has been investigating and developing novel catalysts for the direct cracking of crude to chemicals, in which some refinery steps are bypassed. He has research and development experience in synthesis and post-synthesis modification of catalytic materials (such as zeolites, mesoporous materials, and modified alumina), catalyst characterization and evaluation. Prior to joining Saudi Aramco, Aaron worked as a Lecturer at the University of Manchester, where he lectured on Petroleum Engineering and Chemical Engineering Courses. His research at Manchester University was centered on catalyst development for waste valorization as a strategy for waste management. He researched and developed techniques for the conversion of plastics waste to useful petrochemicals, improving cold flow properties of biodiesel, production of petrochemicals from biodiesel and ammonia remediation in waste streams. Aaron holds a PhD in Chemical Engineering, MSc in Physical Chemistry/Petroleum Engineering and a BSc in Chemistry/Chemical Engineering. He is a Chartered Engineer, Chartered Chemist, Chartered Scientist, Chartered Member of the Institution of Chemical Engineers, and a Member of the Royal Society of Chemistry.
