Yoann Dabrowski

I am an assistant professor at Université Lyon 1 since September 2011, among the Probability and Mathematical Physics group.

Office: Braconnier 227

I coorganize the following conference Probably on Random Matrices.

Main Research Interests

  • Free Probability theory, especially the study of free stochastic differential equations, free entropy, free transport (conjecturally optimal).
  • Applications of free probability to von Neumann algebras.
  • Algebraic quantum field theory.

    • Publications and preprints

    Most of my articles can be found on Arxiv. Links to published versions or preprints can be found below.
