Janosch Ortmann


I am a CRM-ISM postdoctoral fellow at the Centre de recherches mathématiques of the Université de Montréal.

Previously I held a postdoctoral research fellowship at the University of Toronto, working with Jeremy Quastel and Balint Virag. I obtained my PhD at the University of Warwick under the supervision of Neil O'Connell.


Research interests

My main research interest lies in studying random particle systems and polymer models, particularly in the framework of stochastic integrable systems and the KPZ universality theory. The study of these models turns out to have interesting connections with various areas of mathematics, including algebra, queueing theory and combinatorics (via geometric analogues of the Robinson-Schensted-Knuth correspondence).

I am also interested in random matrix theory and probabilistic aspects of free probability theory.
