CNRS - Sorbonne Université (LIP6)



I am currently a PhD Student, since October 2020, at CNRS Sorbonne Université (LIP6) within the TORI project.

My thesis, directed by Julien Tierny, focuses on Topological Data Analysis, especially in the analysis on an ensemble of merge trees with applications in machine learning, visualization and data reduction.

I did my master degree at Paris Descartes University (now Université Paris Cité) in the “Machine Learning for Data Science” track.
