Picture of me

PhD Student in Computer Science, Algorithms Research Group, Université libre de Bruxelles

I am (since October 2020) a PhD student in computer science at ULB under the supervision of Jean Cardinal and John Iacono (funded by the F.N.R.S. with a FRIA grant). I work on questions around fine-grained complexity and optimality for geometric algorithms and data structures.
