Joonas Turunen
I am a postdoctoral researcher at the University of Iceland, Mathematic division. Starting from October 2020, I will be a postdoctoral researcher at the ENS de Lyon. I work on questions arising from the interface of combinatorics, statistical physics and probability. I recently defended my thesis On Ising Model Coupled to Random Planar Triangulations, for which I worked in the Mathematical Physics group at the University of Helsinki. It focuses on random planar maps coupled to the Ising model, which could be viewed as a discrete model of the Liouville Quantum Gravity with matter. To get an idea of this, see my talk in Cambridge, 2018, or a more general online talk. I also work on other random planar map models, both pure and decorated.
