Lyle R. Chinkin is the senior vice president for Emissions, Policy, and Geographic Information Systems Services at Sonoma Technology, Inc. (STI). He also serves as STI’s corporate general manager. Those business areas encompass the preparation and assessment of stationary- and mobile-source emission inventories for use in air-quality analyses and control strategy development. Mr. Chinkin has expertise in emission inventory preparation and assessment and air-quality analyses. He has performed numerous emissioninventory and air-quality studies primarily for government agencies. He also has directed analyses for industrial associations. His work involves emission inventory field measurements, surveys, development, improvement, preparation, and evaluation. Mr. Chinkin earned an M.S. in atmospheric science from the University of California, Davis.
Herek L. Clack is an assistant professor of mechanical and aerospace engineering at the Illinois Institute of Technology in Chicago. His research interests include transport processes within multiphase flows, and design and development of advanced thermofluid processes with application toward combustion and combustion emissions. Currently, his primary research involves developing methods to control mercury emissions from coal-fired electric power plants. In January 2004, Dr. Clack was awarded a National Science Foundation Faculty Early Development CAREER award. He received his Ph.D. in mechanical engineering from the University of California, Berkeley.
John C. Crittenden is the Richard Snell Presidential Chair in the Department of Civil and Environmental Engineering at the Arizona State University (ASU). His research expertise includes sustainability, pollution prevention, physical-chemical treatment processes in air and wastewater, and modeling of fixed-bed reactors and adsorbers. Dr. Crittenden is the codirector of the Sustainable Technologies Program at ASU and directed the National Center for Clean and Industrial and Treatment Technologies (CenCITT) for 10 years. CenCITT conducted research on environmentally responsible manufacturing and involved 60 faculty from 16 academic units and over 200 graduate students. Dr. Crittenden is a member of the National Academy of Engineering. He is an associate editor of the journal Environmental Science and Technology. Dr. Crittenden received a Ph.D. in civil and environmental engineering from the University of Michigan.
