Hello and welcome to my homepage! I discover new mathematics and help people understand and enjoy math.
I am an Associate Professor of Mathematics at the City University of New York. I have a joint appointment in the Mathematics Ph.D program at the Graduate Center and in the Mathematics Department at Brooklyn College.
I am on Faculty Fellowship Leave (sabbatical) for the academic year 2023 - 2024.
My areas of research are combinatorics and geometry – 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, climate science, sociology, art, and the scholarship of teaching and learning.
I did my Ph.d. at Louisiana State University and my dissertation advisor was James Oxley. Interested in matroid theory? Check out my Matroid Theory Pages.
My book "Graphs and Networks" blending graph theory and network science has been published by Wiley. See the Table of Contents. The first chapter is a survey of graph theory and network science and sets the stage for the remaining chapters. The book has a blog accompanying it, where I will be posting all the material that did not make it into the book, as time permits.
I am a co-founder of the New York Combinatorics Group. We welcome all combinatorists in the tri-state area. Send me an email and I'll include you in our growing group. We have been running the New York Combinatorics Seminar, among other things, since 2011. The seminar has a YouTube channel consisting of prior talks.
I serve as the faculty advisor for the Brooklyn College Math Club, and a research mentor for the RAMMP REU, the NYC Discrete Math REU and the Queens Discrete Math REU.
