My name is Olga Romaskevich and I am finishing my first year of my graduate studies in Moscow, Higher School of Economics. Here is my homepage (in Russian): http://www.hse.ru/org/persons/69183417 I'm working in dynamical systems, but I'm as well interested in geometry and combinatorics and their connections with my field. I'm very happy to do mathematics, and interested in broadening my knowledge as well as sharing my knowledge with others, that's why I'm here.
