Inhalation Studies

ROBERT PHALEN Ph.D., co-directs the Air Pollution Health Effects Laboratory at the University of California, Irvine (UCI). He also holds two academic appointments in the College of Health Sciences at UCI: Professor in the Department of Community and Environmental Medicine; and Professor in the Department of Medicine’s Center for Occupational and Environmental Health. He has served as Chair of both the UCI Institutional Review Board (for Human Studies) and the Institutional Animal Care and Use Committee. He is currently a member of the United States Environmental Protection Agency’s Clean Air Scientific Advisory Committee—Particulate Material, and he is a member of 11 professional scientific associations/societies. In 1971, he obtained a Ph.D. in biophysics, with specialization in inhalation toxicology, from the University of Rochester (in Rochester, NY). His postdoctoral research was conducted at the Inhalation Toxicology Research Institute (now the Lovelace Respiratory Research Institute) in Albuquerque, NM. In 1972, Dr. Phalen joined the then College of Medicine at UCI to establish the Air Pollution Health Effects Laboratory, which still conducts studies relating to the toxicology of air pollutants, and trains graduate students and physicians in inhalation toxicology. His research is in several areas including: predicting doses from inhaled particles; health effects of inhaled air pollutants; and applied aerosol physics. He has published over 100 scientific papers, and authored and/or edited four previous books on aerosol inhalation topics.
