Personal profile


Steve Benjamin is Professor of Fluid Dynamics and Director of the Automotive Engineering Applied Research Group at Coventry University. His major research fields at Coventry University have been applied fluid dynamics associated with automotive emissions after-treatment systems and the development and validation of simulation techniques for the prediction of the conversion efficiency of exhaust catalysts for spark ignition and diesel engines.

Prior to this he worked 12 years in the automotive industry at Rover Group and MIRA. At Rover he became head of the Combustion Studies group primarily responsible for the development of combustion systems for four-valve spark ignition engines. At MIRA he was head of the CFD section within the aerodynamics division.

Professor Benjamin obtained his BSc (Mathematics) at Imperial College where he also gained his PhD in air pollution meteorology. Following his PhD he was a postdoctoral fellow at the University of Calgary, Canada researching air pollution dispersion over complex terrain. He works in close collaboration with major OEMs and their suppliers and recently headed a £450K research project funded from the Engineering and Physical Sciences Research Council (EPSRC) investigating selective catalytic reduction on light-duty vehicles. He has published over 90 technical papers and received grants totalling over £3 million.
