UI Caterpillar Lecture On Air Quality Set For Oct. 27

David T. Allen, Melvin H. Gertz Regents Chair in Chemical Engineering and researcher at the Center for Energy and Environmental Resources, University of Texas at Austin, will deliver a Department of Chemical and Biochemical Engineering Caterpillar Colloquium Series Lecture on air quality policy at 3:30 p.m. Thursday, Oct. 27, in Room 3321 of the Seamans Center for the Engineering Arts and Sciences at the University of Iowa College of Engineering.

His free, public talk is titled, "The Texas Air Quality Study: State of the Science of Air Quality in Texas and Implications for Air Quality Policy."

One of the largest U.S. studies of its kind, the Texas Air Quality Study ( involved about 300 air quality investigators from around the world meeting in Houston to gather meteorological and chemical data using five aircraft, five major ground chemistry sites and approximately 20 peripheral sites during August and September of 2000. Allen, one of study's four lead investigators, will give an overview of the study, discuss its policy implications and describe the enhanced understanding of urban atmospheric chlorine chemistry that resulted.

In addition to the 2000 study, Allen has led, or helped to lead, multiple Texas air quality field studies, and his current research uses the results of these air quality science programs to help inform air quality management decisions in Texas. He also serves on state and national committees that advise government agencies on the use of scientific and technical analyses in environmental management decisions. He has served on the National Research Council's Board of Environmental Studies and Toxicology; he serves on the U.S. Environmental Protection Agency's Science Advisory Board, and he chairs the Texas Council on Environmental Technology.  

Allen is the author of four books and over 150 scientific papers and the recipient of numerous awards including: a National Science Foundation (NSF) Presidential Young Investigator Award; AT&T Foundation Industrial Ecology Fellowship; the American Institute of Chemical Engineers Cecil Award, for contributions to environmental engineering; and the State of Texas Governor's Environmental Excellence Award.

He earned his master's degree and doctorate from the California Institute of Technology in 1981 and 1983, respectively. Allen joined the University of Texas in 1995 and previously held faculty appointments at UCLA, the University of California, Santa Barbara and the California Institute of Technology.

The Caterpillar Colloquium Series is made possible by grants awarded to the UI College of Engineering through the UI Foundation by the Caterpillar Foundation of Peoria, Ill. The grants comprise the Caterpillar Excellence Fund, which aids student, faculty and curriculum development in the College of Engineering.

Individuals with disabilities are encouraged to attend all UI-sponsored events. People requiring an accommodation in order to participate in this program are asked to contact in advance the UI College of Engineering Department of Chemical and Biochemical Engineering at 319-335-1400.
