Gregory Fiumara (Fed)

Computer Scientist

Gregory Fiumara has been a Computer Scientist with the National Institute of Standards and Technology (NIST) since 2008. Greg leads NIST's portfolio of fingerprint technology evaluations and contributes to biometric technology standardization efforts worldwide. He serves as an editor in the ISO/IEC JTC 1 biometrics subcommittee. Greg established a new research program for biometric forensic science at NIST, focusing on applied technology for practitioners. This program has produced practical tools such as NIST Special Database 302 and OpenLQM. As an active software developer, he maintains and contributes to open-source projects like NFIQ 2, the reference implementation for the international fingerprint image quality standard. His work on Biometric Evaluation framework, a toolkit facilitating biometric technology evaluation, earned him a U.S. Department of Commerce Silver Medal.

Awards

U.S. Department of Commerce Silver Medal Award for Exceptional Service. "For creating an unprecedented biometric evaluation capability that accelerated forensic standards development and innovation in biometric technology." (2014)
