Research
Research Interests
 network theory
 graph drawings and crossing numbers of graphs
 extremal set theory
 biological applications of discrete mathematics
Current Projects
 Ensemblebased 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 Mpart 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).
