My vita is available, and so are
titles and abstracts of many mathematical talks
You can view my academic family tree.
- Spring 2015: CSC 324, Theory of Computation.
- Spring 2015: Math 113, Calculus II.
- FIFA Foe Fun!,
interactive, personalized rankings of international soccer teams,
for World Cup 2014.
- My page on NCAA Division I
Baseball rankings for 2014, which arose from my teaching
linear algebra. (Look for 2015 rankings later in the spring!)
- During the summer of 2014, I led the
Summer@ICERM program on
Polygons and Polynomials at the
Institute for Computational and
Experimental Research in Mathematics (ICERM) at Brown University,
Robins of Nanyang Technological University.
- I am an associate editor of
Mathematics of Computation.
- My research interests lie in number theory (including analytic,
computational, combinatorial, and transcendental aspects), combinatorics,
and discrete geometry. I am particularly interested in extremal problems
concerning integer polynomials, for instance, problems dealing with
Mahler's measure of a polynomial, problems regarding Barker sequences and
related topics, and problems regarding factors of polynomials with
restricted coefficients. In discrete geometry, I am interested in some
problems regarding convex polygons.
- 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 (Springer-Verlag, 2002).
- The Palmetto Number Theory Series
(PANTS) XX conference on number theory was held at Davidson College on
September 7-8, 2013.
- I maintain a site on
concerning Mahler's measure of polynomials with integer coefficients.
- I also maintain a site on
Barker sequences, and circulant Hadamard matrices.
- 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 co-author of the Maple V Quick Reference (Brooks/Cole,
1994), with Nancy Blachman.
