This semester (Fall 2009), I am teaching:
I am the Math & Stat Departmental Undergraduate Advisor.
If you are already a mathematics major, then probably we've met
in the classroom or for advising.
If some reason we haven't yet met, then I can hardly wait!
Please give me a call or an email or stop by my office soon.
This also applies if you are considering majoring in mathematics, or
even if you just have questions about the math major.
As an advisor, I'm especially useful for
questions pertaining to the Math/Stat Department classes and
undergraduate programs (though I also enjoy talking about
other things). The principal graduate advisor is
Yong Zeng.
For advising on non-math courses and requirements for the BA or BS
degrees, you may also find the
College of Arts & Sciences
Advising Office to be helpful.
I have been an Assistant Professor of Mathematics
at UMKC for six years.
Some prior associations:
Maybe some of you know me from my three years as
a professor at Purdue University, or my five years
as a graduate student at the University of Michigan,
or my twenty-four years attending to various
matters in the state of Minnesota (mostly in Minneapolis,
Northfield, and Edina).

Here is a pamphlet
on permutation models by me. The audience I had in mind was
one undergraduate that I was working with at Purdue University. On
the one hand, it doesn't assume a large set theory background. On the
other hand it does assume some not widely known things,
such as the definition
of "ZFA". Also, I was always around to explain things
verbally, so it's terse in places for a reader with no experience.
Could be some kind of work in progress.
