- Research interests in cryptanalysis, hash functions- Teaching assistant in Java at Ecole Polytechnique

My thesis focused on how data confidentiality can be reached through the use of encryption algorithms and investigated a major class of statistical attacks against block ciphers, denoted as linear cryptanalysis. I published 6 refereed conference papers in Cryptanalysis and one book chapter on Linear Cryptanalysis. As part of the UCL Crypto Group activities, I was involved in the daily management of the group computer infrastructure. I was also teaching assistant and supervised the master thesis of 2 students.
