Research
I work in various areas of discrete mathematics including extremal graphs
and Ramsey theory.
I find it always fascinating when the ideas and techniques from other
areas (such as, for example, linear algebra or Fourier analysis) apply to
combinatorial problems and vice versa. One of such powerfull tools, which
interests me very much, is the probabilistic method.
My recent projects deal with the hypergraph Turan problem, first-order
formulas on graphs, and some questions from combinatorial number theory.
