About Me

Hi, I'm currently working as a PhD student of Léo Ducas at CWI in Amsterdam.

I like working on the border between Mathematics and Computer Science, with a main love for algorithms. Lattices are a returning object in my research: tensored root lattices (BsC Thesis), enumeration of perfect lattices (MsC Thesis), and lattice based cryptanalysis (PhD currently).
