Who am I ?
Short Biography
Born in 1994, I grew up in Belgium. In 2012, I started my bachelor in engineering at UCLouvain Belgium with specific courses on computer science and electronic systems. In 2015, I studied to get a master in Electrical Engineering. There, I discovered security and embedded systems which are the key point of my ongoing research. I concluded my master with a thesis about implementations resilient to Hardware-Trojans.
Research interest
I started my PhD in 2017 under the supervision of François-Xavier Standaert at UCL Crypto Group. I am currently exploring the world of side-channel analysis. In a few words, I am interested in security of electronic devices/embedded systems implementing cryptographic primitives (i.e., block ciphers or PRFs). My research is focused on analysis of software protected implementations. I do my analysis in a open setting where the adversary gets all knowledge/control of the target during the profiling. Recently, I have been involved in the organization of the CHES 2020 CTF
