William Shadel is a senior behavioral scientist at the RAND Corporation. He also is a member of the Biobehavioral Oncology Program at the UPMC-Hillman Cancer Center. Before joining RAND in 2005, he was a faculty member at Brown University and the University of Pittsburgh.

Shadel's research ranges from basic human laboratory work designed to understand the biopsychosocial mechanisms that contribute to smoking initiation and cessation to evaluating cognitive-behavioral and pharmacological smoking cessation interventions in the clinic and public health settings. He has published over 150 peer-reviewed papers and book chapters since 1993 and has been continuously funded as a principal investigator by the National Cancer Institute and National Institute on Drug Abuse since 1999.

Shadel's current grants examine how tobacco advertising at point-of-sale retail locations influences tobacco use behavior in adolescents and adults. He has been or is currently on the editorial board of several journals, was associate editor of the American Psychological Association journal, Psychology of Addictive Behaviors, from 2005 to 2007, and has served as a regular and ad hoc member of several grant review panels at the National Institutes of Health since 1999.

Shadel received his Ph.D. in clinical health psychology and social/personality psychology from the University of Illinois at Chicago.
