Adrien Hardy

Mathematician, Associate professor at Université de Lille, France.

I'm a mathematician mostly interested in probability, statistics, analysis and mathematical physics.

My research interests lie principally in understanding large random interacting particle systems, including random matrix models, determinantal point processes, or Gibbs measures such as the Coulomb gas. More recently, I became interested in using such stochastic models for applications (numerical integration, machine learning, signal processing, telecomunications, ...).

Curriculum

Since September 2015, I am Maître de conférences (~Associate professor) in the Laboratoire Paul Painlevé, which is the mathematic department of the University of Lille.

During 2013-2015, I had a postdoctoral position at the Royal Institute of Technology (KTH) in the research team of Kurt Johansson.

In June 2013, I obtained a joint PhD degree (see the thesis) from KU Leuven, supervised by Arno Kuijlaars, and the Institut de Mathématiques de Toulouse, supervised by Michel Ledoux.

Before that, I studied in the Magistère de mathématiques de Strasbourg, including a Bachelor thesis with Janos Polonyi, a Magistère thesis with Jean-Bernard Zuber (internship at the LPTHE), and a Master thesis with Pierre van Moerbeke (Erasmus exchange program with the Université Catholique de Louvain).
