by Professor Cass focuses on developing methods for identifying the least costly means of air pollution abatement in a complex regional setting. He is currently studying the formation and control of gaseous and fine particle pollutants, control strategies for visibility improvement, indoor air quality, economic optimization of pollution control strategies, and strategies for protection of works of art from damage due to air pollution. He is a member of the research advisory committee for the Health Effects Institute, and a consultant to both government and industry on air pollution and its control. He previously served on the EPA Clean Air Scientific Advisory Committee and on EPA's FACA subcommittee on ozone, fine particles, and regional haze. Dr. Cass served on the NRC Committee on Haze in National Parks and Wilderness Areas and the Committee on Preserving Historical Documents.
