I  work in combinatorics, particularly on extremal problems in a variety of settings including graphs, set-systems and discrete geometry.  A  major topic of my research is finding hypergraph generalizations of  classical  results in graph theory.  

I did my Ph.D. at Central European University in Budapest, Hungary.  Under the  guidance of Gyula O.H. Katona, I wrote my dissertation on extremal problems for partially ordered sets. I have held postdoc positions at the Karlsruhe Institute of Technology, the Discrete Mathematics Group at the Institute for Basic Science, and the Alfréd Rényi Institute of Mathematics.
