Personal Information

Full Name
Neil E. Klepeis, Ph.D.

Neil Klepeis was trained as a physical and theoretical chemist. In pursuing his interests in environmental science, he received his Ph.D. in environmental health, studying indoor air pollutant dynamics and human exposure through computer simulation and controlled laboratory experiments. In addition to his modeling work, he has performed several tobacco smoke air pollution monitoring studies, including a recent study on outdoor tobacco smoke. Since he began working in the exposure field in 1993, he has published many articles and reports on tobacco smoke exposure.
