Ronan Herry

Since January, 2019, I am a wissenschaftlicher Mitarbeiter (research assistant) in Karl-Theodor Sturm group.
In November 2015, I started to prepare a PhD in mathematics under the supervision of Nathael Gozlan and Giovanni Peccati. I defended my thesis on December 3, 2018.
Before that, I was a research intern with Djalil Chafaï in the framework of my master’s thesis.

I am working in the field of Stochastic analysis, Functional inequalities and Optimal transport. My main focus is the use of optimal transport and functional inequalities to study probabilistic models from statistical physics or mechanics, mostly point processes and Liouville quantum gravity measures.

More specifically, I am interested in:

• Stochastic analysis and optimal transport for particle systems.
• Transport inequalities and concentration of measure.
• Functional inequalities for Markov semigroups à la Bakry-Emery.
• Heat kernels, Laplace operators and Ricci curvature on non-smooth spaces.
• Liouville quantum gravity measures in arbitrary dimension.
• Malliavin-Stein approach and limit theorems.

More broadly, I am also interested with many aspects of modern probability such as free probability, rough paths, regularity structures, SPDEs, random geometry, percolation and their interplays with my field of expertise.

2018 Hannan Graduate Student Travel Award (award announcement).

• Since March 2020, I co-organised with Patrik Ferrari and Francesco De Vecchi, the Oberseminar Stochastics in Bonn.
• From September 2016 to March 2017, together with my friend François Petit, I co-organised the PhD Seminar of the mathematics department of the University of Luxembourg.
• In June 2016, I animated a working group on functional inequalities and the KLS and Variance conjecture inside the Probability group.
• From December 2015 to December 2017, I organised an internal seminar in probability where people of the research group explain their current work.
