Patrick Derbez is a postdoctoral researcher at the LACS (Laboratory of Algorithms, Cryptology and Security) in the FSTC (Faculty of Sciences, Technology and Communication) of the University of Luxembourg. He received his M.Sc. degree in Algebra applied to Cryptography from the University of Versailles, France in 2010 and his Ph.D. in Cryptography from the Ecole Normale Supérieure, France in 2013.

His research focuses on techniques for cryptanalysis of symmetric-key cryptographic algorithms. He is particularly interested in automatic attacks finders, and found some of the best known attacks on the AES.
