Biography / Curriculum Vitae

Glenn Langenburg is a certified latent print examiner and owner of Elite Forensic Services, LLC. Previously, he worked at the Minnesota Bureau of Criminal Apprehension for 18 years (13 in the Latent Print Section and 5 as Supervisor of the Drug Chemistry Section).  He also has experience with crime scenes and bloodstain pattern evidence; he was certified as a general criminalist by the American Board of Criminalistics. 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, Australia, Canada, 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.  Glenn had the privilege of serving the fingerprint community as a member of SWGFAST (Scientific Working Group for Friction Ridge Analysis, Study, and Technology) for 10 years.  He has a weekly podcast on fingerprint issues with co-host Eric Ray called the Double Loop Podcast.
