Dr. Richard L. Corsi earned his Ph.D. in civil engineering from the University of California at Davis in 1989. He joined the faculty of The University of Texas at Austin in 1994. Dr. Corsi researches indoor air quality, including sources and control of indoor air pollution and human exposure to indoor toxins. Recently, Corsi studied issues related to chemical and biological attacks in buildings. He researched four chemicals that decontaminate buildings after attacks, how those chemicals react with 24 indoor materials, and the potentially irritating and toxic by-products that form and may persist in buildings for long periods of time. The study has led to knowledge and tools for designing building disinfection systems. Corsi also studies how architectural materials can remove chemicals from building air, offering protection for occupants following terrorist attacks.
