Personal Information

Full Name
Wayne R. Ott, Ph.D.

Wayne Ott has worked on developing new methods to measure, quantify, and predict human exposure to environmental pollutants for 4 decades. This science measures the levels of pollutant concentrations that actually reach people, whether by air, food, water, or skin. He served as an environmental engineer in the Commissioned Corps of the U.S. Public Health Service assigned to USEPA's Office of Research and Development for 30 years. As team leader of USEPA's Air, Toxics, and Radiation Monitoring Research Staff, he coordinated scientific research on measurement methods, quality assurance, nationwide monitoring networks, exposure modeling, and human exposure measurement field surveys. He received the 1995 Jerome J. Weselowski award for his contributions to the knowledge and practice of human exposure analysis and the US Public Health Service Commendation Medal for developing a nationally uniform air pollution index. Since coming to Stanford University from USEPA in 1996, he has continued working on methods to measure and predict human exposure for a wide variety of everyday sources, such as cigarettes, cigars, pipes, candles, incense, cooking, motor vehicles, and wood smoke. He conducted extensive field measurements of exposure to secondhand smoke in California taverns, restaurants, stores, casinos, homes, and automobiles, and he has authored or co-authored more than 100 journal articles, conference presentations, and research reports, including the book Exposure Analysis, the first text book on exposure analysis published by CRC Press in 2007. He is consulting professor, Civil and Environmental Engineering, Stanford University, and visiting scholar at the Department of Statistics.

Wayne Ott's research focuses on making accurate measurements of the pollutant concentrations to which people are exposed from common everyday sources, such as motor vehicles, cooking, wood smoke, incense, cigarettes, and cigars. He helped develop the emerging new science of Exposure Analysis and is co-editor of the first textbook in 2007 in this field. He also conducted statistical analyses of environmental monitoring data and his previous book in 1995 was on Environmental Statistics and Data Analysis.
