Research Interests

Area: discrete mathematics and graph theory with applications to biology and network science.
Results on problems in extremal set theory, crossing numbers, problems related to degree sequences in network science, graph inducibility, enumeration, distance problems in graphs, and algorithmic problems related to bioinformatics. Over 100 invited seminar and conference talks, including two plenary talks. The research was supported by NIH, NSF, DARPA, the Institute of Mathematics and Its Applications, the European Union and the University of South Carolina.
