I am full professor in "Cryptography and Information Security" at the University of Luxembourg in the Computer Science and Communications Research Unit. Formerly I was an associate professor at the same faculty. I am also a faculty member of the Interdisciplinary Centre for Security, Reliability and Trust (SnT).
I am teaching classes on "Information Security Basics", "Symmetric Cryptography and Security of Communications", "Cryptography in the Real World" and guide several Ph.D. students and postdocs.
In the past I was a visiting professor at K.U.Leuven (ESAT, COSIC group), working with Prof. Bart Preneel and participating in the development of European standards for Signature, Integrity and Encryption Schemes (NESSIE project). I have received my M.Sc. and Ph.D. from the Technion - Israel Institute of Technology in 1994 and 1999 respectively working with Prof. Eli Biham, Prof. Shimon Even and Prof. Eyal Kushilevitz. I have been a post-doc at the Computer Science faculty of Weizmann Institute of Science (Rehovot, Israel), working with Prof. Adi Shamir. I have taught graduate courses on "Methods of Cryptanalysis" and "Advanced Symmetric Cryptography" at Weizmann Institute and K.U.Leuven.
I am interested in cryptographic research, especially in cryptanalysis and design of ciphers, hash functions. I am also interested in privacy and anonymity, studying anonymity networks like Tor or crypto-currencies like Bitcoin. I have been a member of International Association for Cryptologic Research (IACR) since 1994. I am frequently invited to program committees of international conferences (around 40 so far) including such top conferences like EUROCRYPT, CRYPTO, ASIACRYPT (with acceptance rates below 1/5).
I am currently the PI of an FNR CORE project ACRYPT on "Lightweight Cryptography for the Internet of Things". I am also MC member of the COST Action IC1403 on "Cryptanalysis of ubiquitous computing systems".
