Leonid Monin
I am currently a Bernoulli instructor at EPFL. Before that I was a postdoc working at the Max Planck Institute for Mathematics in the Sciences in Leipzig and at the University of Bristol. In 2019 I obtained my PhD at the University of
Toronto where I worked with Askold Khovanskii, here is my CV.
You can reach me via my email: leonid.monin@epfl.ch. You might be interested in AdIMOM and our homemade seminars.



Research
I am interested in several areas between algebra and geometry. More specifically, my research can be broadly divided into two parts. The first part is combinatorial algebraic geometry and the second one is Teichmüller theory and moduli spaces. In combinatorial algebraic geometry I am mostly interested in Newton polyhedra theory, toric varieties, enumerative geometry, spherical varieties, and tropical geometry. In Teichmüller theory I am mostly interested in counting problems, geometry of Teichmüller space equipped with Thurston metric, and dilation surfaces.
