Research

Research Interests

  • network theory
  • graph drawings and crossing numbers of graphs
  • extremal set theory
  • biological applications of discrete mathematics

Current Projects

  • Ensemble-based modeling of large graphs and its applications to social networks, collaborative project with L.A. Szekely and researchers in Notre Dame, Houston, Renyi Institute and Rensselaer Polytechnic Institute.
  • Extremal problems: working on resolving our recent conjecture on the maximum size and structure of M-part Sperner systems in a special case; finding connections of Sperner systems to mixed orthogonal arrays (used e.g. in design of experiments) and finding new mixed orthogonal arrays.
  • Crossing numbers of graphs; finding optimal subgraphs with respect to crossing number lower bounds (collaborative work with PhD student Mojca Bracic in Slovenia, whom I coadvise, and others).
