My vita is available, and so are
titles and abstracts of many mathematical talks
of mine.

 Spring 2014: Math 360, Topology.
Research
 During the summer of 2014, I will cohost the
Summer@ICERM program on
Polygons and Polynomials at the
Institute for Computational and
Experimental Research in Mathematics (ICERM) at Brown University,
together with
Sinai
Robins of Nanyang Technological University.
 The Palmetto Number Theory Series
(PANTS) XX conference on number theory was held at Davidson College on
September 78, 2013.
 I am an associate editor of
Mathematics of Computation.
 My research interests lie in number theory, including analytic,
computational, combinatorial, and transcendental aspects. I am particularly
interested in extremal problems concerning integer polynomials, especially
problems dealing with Mahler's measure of a polynomial, and problems
regarding factors of polynomials with restricted coefficients.
I am also interested in some problems in discrete geometry.
 A nice introduction to many of the problems I work on can be found in
the book of P. Borwein, Computational Excursions in Analysis and
Number Theory (SpringerVerlag, 2002).
 I maintain a site on
Lehmer's problem
concerning Mahler's measure of polynomials with integer coefficients.
 I also maintain a site on
Wieferich pairs,
Barker sequences, and circulant Hadamard matrices.
Selected Publications
Books
 The second edition of my textbook Combinatorics and Graph Theory,
written with John Harris
and Jeffry Hirst,
appeared in 2008. It is published by Springer, in the series
Undergraduate Texts in Mathematics.
 The first edition of Combinatorics and Graph Theory,
also published by Springer, appeared in 2000.
 I am coauthor of the Maple V Quick Reference (Brooks/Cole,
1994), with Nancy Blachman.
