My main areas of research are combinatorial optimization and graph theory, and in particular integer multicommodity flows. I am also interested in discrete geometry and problems involving graph metrics.
Additional pages
The tableau, a survey on integer multicommodity flow problems, joint work with András Sebő.
Matching theory (work in progress). A skeleton of a course about matchings.
Presentations
Most of the slides of my presentations can be found on my publication's list. The other presentations are listed below.
Edge-disjoint paths in bounded treewidth graphs. A talk about approximation of the edge-disjoint paths problem in bounded treewidth graphs, when a constant congestion is allowed, joint work with Chandra Chekuri and Bruce Shepherd (2011).
