Original Release Date: March 19, 2018

In episode seven of our 2018 IPTES Season, Just Science interviews Robert Thompson, a Senior Forensic Science Research Manager at the National Institute for Standards and Technology (NIST). Mr. Thompson discusses his research on consecutively manufactured barrels and his recent research on "Objective Comparison of Striated Toolmarks Produced from Ten Consecutively Manufactured Cold Chisels Measured by Contact and Optical Surface Profilometry and Comparison Microscopy". The profile’s similarity and differences were compared using two mathematical methods, cross-correlation function, and the recently developed congruent matching profile segments method.

NIJ and FTCOE are committed to improving the practice of forensic science and strengthening its impact through support of research and development, rigorous technology evaluation and adoption, effective knowledge transfer and education, and comprehensive dissemination of best practices and guidelines to agencies dedicated to combating crime. The future of forensic sciences and its contribution to the public and criminal justice community is a motivating topic to gather expertise in a forum to discuss, learn, and share ideas. The IPTES was specifically designed to bring together practitioners and researchers to enhance information-sharing and promote collaboration among the impression, pattern, and trace evidence analysts, law enforcement, and legal communities.
