I am a permanent researcher within the DataShape research group at INRIA Sophia Antipolis-Méditerranée, France.

My research interests are in Computational Geometry and Topology, with a focus on:

  • Persistent Homology: algorithms, discrete Morse theory, application to geometry and topology.

  • Low-Dimensional Topology: quantum invariants & categorification, combinatorial and computational complexity, normal surface theory, connections with geometry.

I am one of the main creators of the C++ software library GUDHI for Topological Data Analysis; see the Software tab for more details and other coding projects.

I received my PhD in 2014 from the University of Nice and INRIA Sophia Antipolis-Méditerranée, under the supervision of Jean-Daniel Boissonnat. I worked from 2014 to 2017 as postdoctoral fellow within the School of Mathematics and Physics of the University of Queensland, in collaboration with Ben Burton. I started my current position at INRIA in 2018.

I received the Gilles Kahn PhD award in 2015, and an ESA best paper award in 2012.
