Clifford P. Weisel is a professor at the Rutgers University and acting director of the Exposure Science Division of the university's Environmental and Occupational Health Sciences Institute. He also is director of the Doctoral Degree Program in Exposure Science offered by Rutgers University. The focus of Dr. Weisel's research is understanding exposure to chemical agents, with an emphasis on multi-route exposures to environmental contaminants, the association between exposure and adverse health effects, utilization of sensors for continuous exposure measurement, and development and application of biomarkers of exposure. He has examined the relationship among indoor, outdoor and personal exposures to air pollutants, documented the importance of inhalation and dermal exposure to contaminants, characterized exposures within the transportation sector, and examined exposure and health issues related to disinfection by-products in water. He is a past president of the International Society of Exposure Science and has served on numerous international and national advisory committees, workshops and advisory review panels for NAS, EPA, NIEHS, CDC, state governmental, environmental groups and private industry and as associate editor of the Journal of Exposure Science and Environmental Epidemiology. Dr. Weisel has authored or co-authored more than 100 peer-reviewed publications and book chapters and authored with Dr. Paul Lioy the book Exposure Science: Basic Principles and Applications.
