Books

My first book, A Walk Through Combinatorics, was published by World Scientific, first in 2002. The second edition was published at the end of 2006. This is an undergraduate textbook on general combinatorics. Click here for some info about this book, such as the table of contents, schools that use it, and reviews of the book. The third edition of this book has been published in Summer of 2011. It has two extra chapters, one on block designs and one on counting unlabeled structures.

My second book, Combinatorics of Permutations, was published in June of 2004. This is a textbook for a special topic Graduate Course. The publisher is Chapman-Hall and CRC Press. Click here for some info about this book.

My third book, Introduction to Enumerative Combinatorics, was published by MacGraw-Hill, with a copyright year of 2007. It is available for purchase at Amazon.com . This is a textbook that focuses on Enumerative Combinatorics and that can be used at a variety of levels. Focusing on Part I, one can teach an undergraduate class from it, and focusing on Parts II and III, one can use it for an introductory graduate class. Click here for some info about this book. The first review is in!

I have co-written a Calculus text, Concepts in Calculus I, with my colleague Sergey Shabanov, commissioned by the University of Florida, and published by the University Press of Florida. This is part of the University of Florida Online Calculus Initiative.

Funded Research

An earlier joint grant proposal, written with Meera Sitharam and Mavis McKenna and submitted to the National Science Fundation and the National Institute of General Medical Sciences was accepted in the Summer of 2007. This interdisciplinary grant ran for four years, and carried a total value of 548,660 dollars.

In 2007, I was awarded a 10K grant for undergraduate research in the Life Sciences by the Howard Hughes Medical Institute. See the press release.

I am grateful for support by the National Security Agency. The NSA supported my research through three grants, in 2003-04, in 2005-06, and in 2007-08.

Teaching

In Spring 2012, I teach Complex Functions in One Variable, MAA 4402, also running as MAA 5404. Here is the syllabus for this course.

I also teach a graduate course, MAD 7397, on the Combinatorics of Permutations. Here is the syllabus for that course.

Service

I am one of the editors-in-chief for the Electronic Journal of Combinatorics.

I am currently co-organizing two special sessions at various AMS Meetings. One is a special session on Analytic Combinatorics in Syracuse, NY, on October 2-3, 2010, and the other is a special session on Applied Combinatorics in Statesboro, GA, in March of 2011.
