From 2005 to 2008, he was detached from Gipsa-Lab to work as a visiting researcher at the Computer and Information Science Laboratory in the Helsinki University of Technology, Finland. His research interests include steganography, steganalysis, forensics and security evaluation of watermarking schemes. From 2004 to 2008, he was co-coordinator of the virtual lab 1 on “watermarking and theory” within the Ecrypt European NoE. He has co-organized the 9th International Workshop on Information Hiding (IH07), the 2nd Edition of the Bows-2 contest on watermarking in 2007, the first edition of the BOSS contest on steganalysis in 2010 and the Alaska contest in 2020. From 2013 to 2016 and 2018 to 2023 Patrick Bas was associate editor of IEEE Transactions of Information Forensics and Security (IEEE TIFS). He is currently Senior Associate Editor for the same journal. Patrick Bas is the current co-group leader of DATING group in the CRISTAL Lab.
