My research interest are as follows, where the most recent topics are listed first, but not necessarily what I am most interested in.

Here is a pdf version of my CV (Curriculum Vitae).
Here are pdf versions of some articles of mine.

I have had the pleasure and honor to collaborate with the following people.

Book on graph theory

My graph theory book that my co-author Ray Greenlaw and I wrote together, has been published by Pearson Prentice Hall in Septemeber 2006. The official year of the book, however, is 2007 (I guess this works the same way as with cars: the NEW X model of each and every car is always available in the year X-1!).

I will try to maintain an ERRATA sheet for various typos and mistakes that we the authors find and that also keep trickling in from the users of this book. Further comments and related references are always welcomed! -- Sincere thanks to Prof. Robert W. Robinson at The University of Georgia (UGA) and the students of his Math(CSCI) -- 4690/6690 graph theory class of Spring 2009, who used this textbook and found numerous typos and other small (yet embarrassing!) mistakes.

Complete solutions to a selected number of exercises are available from the publisher, Pearson Prentice Hall. Instructors should contact the Editorial Assistant, Jennifer Lonschein (Email: Jennifer_Lonschein at prenhall dot com, Phone: (201) 236-7739) for the solutions. -- Needless to say, comments on typos and other SNAFUs in these solutions are always welcomed!


I currently have one Ph.D. student Jill Bigley Dunham. She plans to graduate in 2009. Her thesis work is on coin graph in the Euclidean plane.

Jill will be giving a talk in the AMS Special Session on Convex and Discrete Geometry in the 2009 Joint Mathematics Meetings of the AMS and MAA in DC January 5 -- 8.


In the Spring Semester of 2009, I will teach the following courses:

A conference

In the Fall Semester of 2004, Jay Shapiro and I organized the Mid-Atlantic Algebra Conference 2004, a weekend-long conference here at GMU, involving a good group of algebraists, discrete mathematicians and computer scientists.

I do have a few copies of the Mid-Atlantic Algebra Conference Pseudo Proceedings (or just the MA2P2.) If you did not receive a copy after the conference, or are just interested in obtaining a copy, then drop me an email and I will be happy to snail-mail you one. These pseudo proceedings contain the abstracts and the talks of the invited talk and the contributed talks as they were presented at the conference.

Other Non-professional Stuff
