  This workshop aims to provide forensic practitioners, laboratory managers, legal personnel, and
researchers with knowledge of emerging tools and technologies for forensic firearm and toolmark
analysis. Training topics include the theory behind different styles of microscopes for measuring threedimensional (3D) toolmark topography, measurement quality assurance, data processing methods,
quantitative toolmark similarity metrics, statistical frameworks for estimating the strength of the
evidence, and virtual comparison microscopy. Participants will learn about the advantages and current
limitations of these emerging technologies, and about strategies for their implementation in casework. 9:00 - 9:30 am Introduction to NIST and the Firearm Toolmark
