I work on systems that turn raw energy resources into useful energy outputs. These processes include combustion, heat recovery and energy harvesting (e.g., advanced cycles, engines, thermoelectrics), and availability recovery (e.g., solid oxide fuel cell cycles). We emphasize the control of environmental pollutants. Past and present projects include mercury capture in combustion processes; the formation of submicron mineral aerosols in biomass and coal combustion; the control of carbon particles in wood burning hydronic furnaces; and the control of NOx emissions when using alternate fuels in gas turbine combustors. I have worked in industrial research for 12 years with a subsidiary of GE Energy Systems before joining the UW. Thus, much of my research relates to using fundamentals to solve practical industrial problems.
