CSAFE was an exhibitor at the 2022 AAFS Conference.

The Center for Statistics and Applications in Forensic Evidence (CSAFE) researchers and staff will attend the American Academy of Forensic Sciences (AAFS) annual scientific conference. The conference will be held Feb. 13–18 in Orlando, Fla.

CSAFE will be in booth 320 in the Exhibit Hall starting on Wednesday, Feb. 15 through Friday, Feb. 17. Visitors to the booth will be able to learn all about CSAFE’s new online learning platform, CSAFE Learning, and can sign up for all new courses and learning opportunities. They can also test their knowledge of forensic statistics by playing the game FastStats.

CSAFE researchers will also share the latest advancements in their research activities, including firearms, handwriting, and latent print analysis; forensic methods for digital evidence; and using statistical methods in forensic science. Below is the list of CSAFE presentations, workshops and poster submissions. In addition, there are a few presentations from CSAFE’s board members and research collaborators.
