Thomas A. Cahill, Ph.D., is a professor of physics at the University of California, Davis. His early work at UCLA, in France, and in Davis, California, was in nuclear physics/astrophysics, but he soon began applying physical techniques to applied problems, especially air pollution. His data in 1973 on the impacts of airborne lead was instrumental in the final establishment of the catalytic converter in California in 1976. He proposed and supported the law to lower sulfur in gasoline in 1977. He was director of both the Institute of Ecology and the Crocker Nuclear Laboratory, which included work on analyzing ancient documents. He spent the following 20 years designing, building, and running the aerosol network to protect visibility at U.S. national parks and monuments – now the national IMPROVE program. In 1994, he founded the UC Davis DELTA Group to work in two areas: aerosols and global climate change, for the National Science Foundation (NSF) and the National Oceanic and Atmospheric Association (NOAA). Additionally his group analyzed aerosols and human health impacts for the California Air Resources Board, American Lung Association, and the Health Effects Task Force for Breathe California of Sacramento Emigrant Trails. It was this health-related work that brought him into the health of workers at the 9/11 collapse site, where he was one of the first to predict serious health impacts that have now, regretfully, occurred. While he has authored or co-authored hundreds of academic articles and book chapters, Annals of the Omega Project is his first work of science fiction.
