Glenn Langenburg, Ph.D., CLPE, F-ABC


Glenn Langenburg is a certified latent print examiner at the Minnesota Bureau of Criminal Apprehension.  He has experience with crime scenes and bloodstain pattern evidence and he is certified as a general criminalist by the American Board of Criminalistics.  Glenn has a B.S. in Forensic Science from Michigan State University and a M.S. in Analytical Chemistry from the University of Minnesota.  Glenn has a Ph.D. in Forensic Science from the University of Lausanne in Switzerland. His thesis, “A Critical Analysis and Study of the ACE-V Process”, focuses on decision-making and the application of ACE-V by fingerprint experts.  Glenn has lectured and hosted workshops nationally and internationally at forensic science conferences in the United States, Canada, Australia, and Europe on topics including Daubert issues, research, probabilistic approach, error rates, and fingerprint methodology.  He has published numerous research articles in peer reviewed journals.  He also co-hosts a weekly podcast, “The Double Loop Podcast”, on fingerprint topics with Eric Ray.  Most recently, Glenn has taken on a new role at the Minnesota BCA as a Forensic Science Supervisor of the Drug Chemistry Section.
