During 2019, CSAFE researchers joined world-renowned forensic science professionals at prestigious conferences across the country. Center team members shared the latest CSAFE advancements through invited talks, poster and oral presentations.
Conference attendance at key events hosted by the American Academy of Forensic Science (AAFS), the Association for Firearms and Toolmark Examiner (AFTE), and the International Association for Identification (IAI) allows CSAFE to make valuable connections with the forensic community, learning directly from practitioners what they need and how CSAFE can help.
Together, researchers and forensic practitioners learn from each other about new methods, research, and education- discussing ways to move forensic science forward.
CSAFE researchers will present at the upcoming IAI conference in August. Please join us to learn more about our research, and stop by our booth to share ideas and discuss collaboration opportunities.
If you didn’t have the chance to connect with CSAFE at the AAFS and AFTE conferences this year, review a sampling of our presentations below. If you are interested in learning more about any of these projects, please contacts us.

- Automatic Matching of Hamby Sets: Friends, False Friends, and Clones
Over the past year, we have had the opportunity to scan several Hamby Sets from different Forensic Labs. Scans from another two Hamby sets are available from the National Ballistics and Toolmarks Research Database. We were also given two clone sets by Prof Hamby. This gave us at least twelve bullets from each of the barrels and allowed us to turn the tables: Instead of matching bullets to bullets, we can now take a look at how well each of the ten barrels marks and how much variability we see in the scores for each of the barrels. Using the automatic matching algorithm, we were also able to evaluate the clone bullets in more detail and compare scores from clone to clone and clone to bullet. Results show that clones generally result in lower scores, but are still identified as matches to bullets from the same barrel.
