Hi. I'm a professor in the Department of Mathematics and
Statistics at San José State
Office: MacQuarrie Hall 419.

that I no longer use my old email address firstname.lastname@example.org.

I'm the advisor of many of our students getting BA's in Math (the pure
option), so if you need advice on your undergraduate degree,
please contact me, and I can at
least put you in touch with someone who can help.
for more information on SJSU math advising, or more specifically,
undergraduate math majors at SJSU.
This semester (Spring 2018), I'm teaching:
Other teaching things:
- How to minor or major
in math at SJSU, the very short version.
- Handouts on writing math in
paragraph style and writing
proofs (revised August 2008). The first handout is for anyone
learning to write up solutions to math problems in complete
sentences. The second is aimed at students who know a little bit of
linear algebra, but should be useful for anyone learning how to
write proofs, since it doesn't really rely on any knowledge of
linear algebra. (Someday, I want to turn the second handout into a
book; please contact me if
(a) you're a publisher, (b) you find the idea interesting, and (c)
you can figure out a way to charge less than $10 for it.)
- A related handout (taken from the proof notes) about how to give a lecture on
- Handout on how to do well
in college math, especially for beginning students. In three
words: Do your homework!

My research interests are in various areas of discrete mathematics,
especially group theory, which is the mathematical study of symmetry
through abstract algebra. I am also interested in other topics in
algebra and combinatorics. More specifically, my interests include:
In the past, I've also been interested in lattices, knots, discrete
subgroups of Lie groups, automorphic forms and functions, ideas
related to the inverse Galois problem (e.g., dessins d'enfants) and
- Geometric group theory, especially groups of non-positive
- Combinatorics of partially ordered sets (extremal set theory);
- l2 invariants, like homology and cohomology,
which I gather falls under the buzzword of noncommutative geometry;
- Combinatorial game theory, including 0-player games (cellular
- Sporadic finite simple groups, and related phenomena, like
Moonshine and Moufang loops; and
- Modular groups and braid groups of various types.
If you want more details, here are my academic vitals.
- Curriculum vitae with annotated bibliography (includes links to
postscript/pdf preprints of many papers)
- Nicely formatted printable version of my CV: pdf. (Version without abstracts: pdf; version emphasizing discrete
math, for industry: pdf.)
A very old but still shameless self-promotion! My research monograph,
Quilts: Central extensions, braid actions, and finite groups,
is available as Springer
Lecture Notes in Mathematics vol. 1731 (listing on
amazon.com, though now out of print).
