Much of my work involves characterizing emission rates from various types of emission
sources, including major stationary sources such as power plants, and mobile sources
such as highway vehicles. I am interested in identifying methods for preventing the
formation of air pollution, such as through better process design in the case of
power generation or through better management in the case of highway systems. Air
pollution control technologies are sometimes the most effective approach for reducing
emissions of air pollutants. For more than ten years, I have done work in modeling
and assessment of air pollution control technologies. This work has been primarily
with respect to coal-based power generation technologies, but includes air pollution
control from natural gas and oil-fired power plants as well as from a wide variety
of other emission sources.
