Welcome to our virtual poster session! The Forensic Technology Center of Excellence (FTCoE) would like to highlight student research in the forensic sciences! The FTCoE is grateful for all the universities, faculty, and students who took the time to prepare poster presentations for submission to this year’s event. We recognize your hard work, and we are here to celebrate and learn from your research.

Using a typical OEM paint system, the PDQ Maintenance Team will walk through the best practices to efficiently use the database and spectral libraries to identify the most likely source of an unknown paint system. Details gathered from this process include manufacturing plant, year range, and models.

The focus of this project was the application and limitations of technology used for fire investigations. Today’s field-portable GC/MS) systems were found to provide lab-quality data for volatile hydrocarbons but the interpretation of that data proved challenging for field operators. Online access to lab experts is essential.  Evidence sampling is enhanced with the use of sensitive Photoionization Detectors (PID) as a supplement to canine searches.
