Peter Peer is a full professor at the Faculty of Computer and Information Science at the University of Ljubljana, Slovenia, where he also heads the Computer Vision Laboratory, coordinates the double degree study programme with the Kyungpook National University, South Korea, and serves as the Vice Dean for Economic Affairs. He received his PhD from the same institution in 2003, after which he was an invited post-doc researcher at CEIT in San Sebastian, Spain. His field of research is computer vision with a focus on biometrics. He participated in several national and EU funded R&D projects and (co-)authored over 100 research papers in respected scientific peer-reviewed journals and conferences related to computer vision, image processing, pattern recognition, and biometrics. He co-organised the Unconstrained Ear Recognition Challenge at the IEEE/IAPR International Joint Conference on Biometrics in 2017 and at the IAPR International Conference on Biometrics. In 2018 he was a co-editor of an IET Biometrics special issue on ear recognition. He currently serves as an associate editor for IEEE Access and IET Biometrics. He is a memeber of EAB, IAPR, and IEEE. He also served for 4 years as chairman of the Slovenian IEEE Computer chapter.
