Bill received his PhD from the University of Florida in 1997 and his BS from Virginia Tech in 1992, both in Chemical Engineering. He followed a relatively unique career path that has given him a broad perspective in the field of environmental catalysis, including catalyst design, manufacture, characterization and application. This was gained by working across a spectrum of locations; a national lab (Pacific Northwest National Lab), a catalyst manufacturing company (EmeraChem), and an engine manufacturer (Cummins Inc) before he returned to academia (University of Waterloo, University of Houston and now University of Virginia). His research has most recently focused on diesel engine emissions reduction, catalyst degradation and how catalyst surfaces change with reaction conditions.
