Patrick Grother is a scientist at the National Institute of Standards in Technology responsible for biometric algorithm evaluation, and biometric performance testing standardization. He leads the Face Recognition Vendor Tests, the Face-In-Video Evaluation and the Iris Exchange projects which constitute the world’s largest independent public tests of biometric algorithms. The results provide quantitative support to developers, end-users, and policy makers faced with algorithm selection, performance adequacy assessment, and procurement specification. Grother’s current research interests relate biometric failure analysis, image quality, demographic effects, and scalability. He co-chairs NIST’s biannual International Face Performance Conference (IFPC) on measurement, metrics, and certification. He also assists several US Government agencies in biometrics performance assessment and standardization. Since 2018, Grother has served as the chairman of the ISO/IEC/JTC 1 Subcommittee 37 on Biometrics where he has edited seven performance testing and data interchange standards. He received the IEC 1906 Award in 2009 and the ANSI Lohse IT Medal in 2013.
