Postdoctoral researcher in applied mathematics, Université catholique de Louvain, Belgium

I am a postdoctoral researcher (teaching assistant) at UCLouvain, Belgium, in the mathematical engineering department (which is part of the ICTEAM institute).

Before that, I graduated as an engineer in applied mathematics at UCLouvain in 2015, and got a PhD in mathematical engineering at UCLouvain in 2019, under the supervision of Julien Hendrickx and Pierre-Antoine Absil.

My research lies in the continuity of recent works developing "structure-aware" fitting algorithms, i.e., data fitting algorithms that take into account the structure of the data. The data points are here assumed to lie on a Riemannian manifold. During my PhD, I have mainly focused on two problems: averaging a set of positive-definite matrices and fitting a curve to a set of fixed-rank positive-semidefinite matrices.
