Faculty, students and staff from the Center for Statistics and Applications in Forensic Evidence (CSAFE) participated in the 2022 International Association for Identification (IAI) Annual Educational Conference. The conference was held July 31-Aug. 6 in Omaha, Neb.
CSAFE was a conference sponsor and hosted the mid-week Discipline Social Event on Aug. 3. The Center also had a booth in the exhibit hall where attendees could watch technology demonstrations, including a custom-built footwear scanner and a handwriting analysis software app.
Nine posters from CSAFE researchers were submitted in the poster session held Aug. 2, including posters from the students who participated in CSAFE’s Research for Undergraduate Students (REU) summer program. The IAI poster session marked the end of the REU internship experience and allowed the students to present their final research results. Below is the list of researchers with a link to view their posters.
