Biography and expertise
Lucas Rusnak received his Ph.D from Binghamton University in 2010. His research is in oriented hypergraphs and combinatorial matrix theory. He is particularly interested in generalizations of the structural and matroidal properties of signed and gain graphs, as well as the roles frustration and balance play in oriented hypergraphs.
