#### Education

B.A. Mathematics, University of California, Santa Barbara,
1988.

Ph.D. Mathematics, University of Illinois at Urbana-Champaign,
1994. Thesis Advisor: L. van den Dries.

#### Research Interests

I am interested primarily in applications of
logic---specifically, model theory---to real analytic geometry,
geometric measure theory, asymptotic analysis, and questions of
differentiability and analyticity of real functions, via studying
sets and functions that are definable in "well-behaved'' (e.g.,
o-minimal) first-order structures on the field of real numbers.
Determining which structures should be regarded as well behaved is
part of the job.

NOTE: As of May
13, 2011, I will no longer be posting any new NSF-supported
(as opposed to older or updated) research material here, because I
do not want to deal with the current NSF requirements for posting on
personal web pages.Rather, I will post new NSF-supported material on
preprint servers such as arXiv and MODNET.
Please contact me for e- or offprints of papers that have already
been published.
