General information

Research

I am working on different problems of discrete geometry and combinatorics. My current research interests are parallelohedra theory (in particular, the Voronoi conjecture on parallelohedra), geometrical properties of quasicrystals (wobbling and bilipschitz equivalence to a lattice), and measures equipartitions.

You can find some more structured information below, or in my CV.

Teaching

Currently (Fall 2018) I am teaching the following courses:

  • MATH 2412-14 Precalculus;
  • MATH 2414-12 Calculus II.
