I am a postdoctoral researcher at KU Leuven, in the COSIC group. I defended my PhD thesis `A geometric approach to symmetric-key cryptanalysis’ in June 2023. My promotor was Vincent Rijmen. Contact information:

My main research program is the development of the geometric approach to symmetric-key cryptanalysis. Specifically, I am actively working on the following topics related to the geometric approach:
- Applications of quasidifferential trails.
- Ultrametric integral cryptanalysis.
- Combinatorial theory of cryptanalysis.

I occasionally work in information-theoretical cryptography (sometimes called "provable security"). My research interests in this area include:
- Generic attacks on information-theoretical constructions.
- Development of new proof techniques.
- Design of new constructions (to a limited extent) .

I have worked on several other topics in cryptography, including
- Applications of cryptanalysis to the theoretical analysis of side-channel countermeasures.
- Cryptanalysis of unusual cryptographic primitives, such as the Legendre PRF.
