My area of research is combinatorics - matroid theory, graph theory, and combinatorial algorithms with applications to network science. My areas of interest are broader and include linear and abstract algebra, probability, statistics, history of mathematics, and climate science.

Publications and Talks

My research is supported by the following grants:

  • Faculty Fellowship Leave (July 2016 - June 2017)

  • PSC CUNY grants (July 2010-June 2016):
    (Award Numbers 68341-00 46, 67151-00 45, 66305-00 44, 65064-00 43, 64181-00 42, 63076-00 41)

The Matroid Theory Pages have among other things a large bibliography of matroid papers and links to my matroid software Oid

Teaching-related activities are located at the Teaching Activities Pages.

Details of service activities are listed in the Brooklyn College Faculty Profile.

I organize the New York Combinatorics Seminar, on Fridays at 11:30 am at the Graduate Center together with Deepak Bal, Jonathan Cutler, Ezra Halleck, Sandra Kingan, Joseph Malkevitch , and Kerry Ojakian.

I also organize the Brooklyn College Mathematical Sciences Colloquium with David Aulicino

On Feb 22 2017 Benjamin Carp and I organized a workshop on "Surveillance and the First Amendment." It was live streamed on Facebook and is available in full here. I opened the workshop and my talk is at the end.

More events from the "We stand against hate" initiative are here.

In June 2016 Kira Adaricheva and I organized a minisymposium on Matroids and Antimatroids at the SIAM Discrete Math Conference.

In March 2012 Joe Bonin and I organized the special session on Matroid Theory at the American Mathematical Society (Eastern Section) meeting in Washington DC.
