My Research Activities
I am interested in most areas of discrete mathematics and combinatorics. Most of my research has been so far in graph theory, matroid theory, coding theory, combinatorial polynomials, combinatorial matrix theory, design theory, partially ordered sets, matching theory, flow theory, and enumerative combinatorics. Most of my research is highly foundational and theoretical but I also enjoy applying combinatorial methods and results to other areas, so far including big data in medicine, bioinformatics, criminology, ecology, electrochemistry, energy-storage, law, linear algebra, oceanography, psycholinguistics, quantum mechanics and renewable energy. I also very much welcome the opportunity to solve tangible real-life problems and have consulted for a variety of companies and government.
If you have any problem that might benefit from some math- or problem-solving skills, then please email me!
