Pavel Korshunov

Short Biography

Pavel Korshunov (Google Scholar) is a research associate in Biometrics Security and Privacy (BSP) group (head of the group: Dr. Sebastien Marcel) at Idiap Research Institute (Martigny, Switzerland), currently working on sythetic data (audio and video deepfakes, fake documents, sythetic images) generation and detection, age verification, and fact checking. He received his Ph.D. in Computer Science from School of Computing, National University of Singapore (advisor: Dr. Wei Tsang Ooi) in 2011 and was a postdoctoral researcher in MMSPG (head of the group: Dr. Touradj Ebrahimi) at EPFL (Lausanne, Switzerland) from 2011 till 2015. He is a recipient of ACM TOMM Nicolas D. Georganas Best Paper Award in 2011, two top 10% best paper awards in MMSP 2014, top 10% best paper award in ICIP 2014, and best paper award in ICML workshop in 2019. He has over 80 research publications, and he is a co-editor of the JPEG XT standard for HDR images. He is one of the contributors to the signal processing and machine learning open source toolbox Bob.
