My main research interests lie in topological graph theory, a branch of discrete mathematics that deals with embeddings of graphs on various types of surfaces. I am particularly interested in embeddings with highest degree of symmetry. Such embeddings are called regular maps and they have surprisingly deep connections with groups, Riemann surfaces, and Galois theory. On a broader scale, I like applications of algebraic methods in graph theory, and therefore topics such as vertex-transitivity, Cayley graphs and maps, or the degree-diameter problem, belong to my favourites as well.

As regards leisure interests, the top two are classical music (I play piano) and mountain hiking.
