# Leonid Monin

 I am a Research Associate at the University of Bristol funded by EPSRC. Currently I am working with Fatemeh Mohammadi. In 2019 I obtained my PhD at the University of Toronto where I worked with Askold Khovanskii, here is my CV. You can find me in my office 2.06 in Fry Building or reach via my email: leonid.monin@bristol.ac.uk. 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.
