About Me

Hi, currently I am working as a post-doctoral researcher in the Number Theory group at the Institut de Mathématiques de Bordeaux. From 2018 to 2022 I was a PhD student of Léo Ducas at CWI in Amsterdam, and I obtained my doctorate at Leiden University in February 2023.

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).
