**RESEARCH POSITIONS**

**Cornell University,**

**Center for Communications Research**, Princeton, NJ, Summer '93, '94,
'01, '02, '04

Summer Conference on Applied Math Problems (SCAMP).
I contributed to the company's team oriented approach to
classified Department of Defense mathematics research.

**BARRA, Inc.**, Berkeley, CA, Summer '98

I analyzed a model of Merton's problem of lifetime asset allocation
using stochastic calculus, supervised by Dr. Nicolo Torre.

**University of Minnesota**, Duluth, Summer '92

I constructed an algorithm to demonstrate the bandwidth of a certain class
of graph theoretic trees as a participant in a National Science Foundation
Research Experience for Undergraduates (REU) directed by Professor Joseph
Gallian.

**Rose Hulman Institute of Technology**, Terre Haute, IN, Summer '91

I researched problems on a generalization of commutativity
in finite groups.
Professor Gary Sherman directed this National Science Foundation REU.

**Cornell National Supercomputing Facility**, Ithaca, NY, Summer 1990

I implemented an original parallel algorithm for reduction of
a matrix to Hessenberg form, a preparatory step for determining
eigenvalues. The project derived from my Westinghouse
Science Talent Search semifinalist winning entry. Helen Doerr
directed the SuperQuest Supercomputing Institute.

**TEACHING EXPERIENCE**

**Cornell University** from Fall 2000.

I have taught Linear Algebra, Abstract Algebra,
Calculus, and Introduction to Number Theory.
In Spring 2003, I will teach a
new course on Cryptography.
In Fall 2002, I was nominated for the departmental
teaching prize.

**Harvard University** and **University of California**,
various academic terms, '91-'99

As teaching assistant, I led discussion sections, graded exams and
homework, and conducted office hours for undergraduate math and computer
science. I was awarded a
citation for teaching excellence in '93 at Harvard and '98 at Berkeley.

**PROFESSIONAL SERVICE**

I organized the Berkeley math graduate student colloquium
in 1997-8.

I served on the Cornell math department committee to award the Ithaca High
School senior math prize in '01, '02, and '03.

I organized a new seminar at Ithaca High School for their dozen students
who completed the math and related courses offered, with David Bock,
of Ithaca HS, and several Cornell math graduate students.

I presented a module on Cryptography for high school students
as part of Cornell Math Department's Math Explorers Club outreach program.
