Associate Professor, Virginia Commonwealth UniversityDr. Thomas Eissenberg, Associate Professor in Virginia Commonwealth University's Department of Psychology and Institute for Drug and Alcohol Studies, obtained his doctorate in experimental psychology in 1994 from McMaster University in Hamilton, Ontario. He then spent two years as a postdoctoral fellow in the Behavioral Pharmacology Research Unit at theJohns Hopkins University School of Medicine before joining the VCU faculty in 1997. At VCU, Dr. Eissenberg's research involves understanding how gender and pharmacologic and associative factors influence tobacco use and tobacco/ nicotine withdrawal. Another research focus involves developingclinical laboratory methods that can be used to predict if potential reduced- exposure products for tobacco users will actually reduce tobacco- related disease and death. He is also involved in an international collaboration with the Syrian Center for Tobacco Studies to investigate the short- and long- term effects of tobacco smoking using a waterpipe. Dr. Eissenberg's work is supported by the National Institute on Drug Abuse, the National Cancer Institute, and the Fogarty International Center.
