Dr. Bill Lewinski – Force Science


Dr. Bill Lewinski is the co-founder and executive director of The Force Science Institute, which was launched in June 2004 and is headquartered, Minnesota. The Institute’s mission is to scientifically determine and fully understand the true dynamics of force encounters – what actually happens between officers and offenders in fluid, rapidly unfolding, site, life or-death confrontations.

 Dr. Lewinski has a Ph.D. in police psychology, a subject he has studied for more than three decades. He is a full professor in the Law Enforcement Program at Minnesota State University, Mankato where until recently he taught full-time for more than two decades.

 He has interviewed more than 1,000 officers who have been involved in deadly force incidents and he has conducted groundbreaking research that sheds light on the little understood and often ignored realities of deadly force encounters. This information has saved officers’ lives on the street and has prevented some from going to prison when they were wrongly accused of criminally using deadly force.

 Force Science Institute findings combined with Dr. Lewinski’s expert courtroom testimony have made a dramatic impact on some of the highest profile use-of-force cases in the U.S. and the United Kingdom. His research has been published in numerous national law enforcement publications and e-newsletters. Additionally, the work for The Force Science Institute is frequently cited in law enforcement training articles and classes worldwide.
