Senior Research Scientist
Dr. William B. Hansen received an honors bachelor of arts degree from the University of Utah in 1974, a Master of Science degree in 1977, and a Ph.D. in 1978 in social psychology, both from the University of Houston. He has served on the faculty at UCLA (1978-1984), the University of Southern California (1980-1989) and Bowman Gray School of Medicine (1989-1996).
He has been the Principal Investigator or Project Director on numerous grants and contracts and is a widely recognized expert in alcohol and drug prevention. He has written numerous curricula for school and community-based prevention, including Project SMART, Project STAR, and All Stars. He has authored over 130 articles in scientific journals on research and evaluation methods, prevention theory, and strategies for successful prevention practice. In 2001, he was the recipient of the Society for Prevention Research “Science to Practice” award, recognizing his contribution to designing evidence-based approaches to prevention that can be used in real world settings. In 2013, he was named a Fellow of the Society for Prevention Research.
