Current Projects
I am a Professor of Mathematics at the University of Washington in the sometimes
sunny city of
Seattle. Here is my curriculum
vitae which "provides an overview of a person's life and
qualifications" according to Wikipedia. See also my Google scholar page.
Below are some of my current projects:
 Teaching: This fall 2018, I will be teaching Discrete
Mathematical Modeling.
 Research: I will be going to ECCO 2018 in Colombia,
Permutation Patterns and FPSAC at Dartmouth, and an ICM
Satellite Conference at the University of Miami.
 Seminar: I organize the Combinatorics Seminar at
UW with Isabella Novik and Connor Sawaske.
 Science Fiction in Action: Graphlopedia:
A fingerprint database of graphs. More coming soon!
 Community: Timea Tihanyi from the School of Art, Art History
and I are the 2018 recipients of the
UW College of Arts and Sciencesâ€™ Bergstrom Award for Art and
Science. Here is a bit of our collaboration at
Slip Rabbit
Studio.
 Community: I am the faculty mentor for the UW Student Chapter of
the
Association for Women in Mathematics (AWM). I am also
on the Policy and Advocacy committee this year for AWM.

Mathday: I speak (almost) every year at Mathday; one of the biggest
mathematical events for high school students in the country
where this year 1650 students came to campus for a smorgasbord of
mathematical experiences. In the past I have talked about
mathematical card tricks, Sudoku, math of the web, the
GaleShapley algorithm and
computer proof techniques, ranking models like US News and World Reports. A few years ago, I gave the plenary
lecture. Video under the talks link. This year I talked about
Bitcoin, Blockchain and the Boogeyman behind it.
 In the news: I often teach Math 381: Discrete Mathematical
Modeling. In order to learn about the modeling process, we study
real world problems that affect real people. We will seek out and
solve problems related to the community around us. The course
culminates in a final modeling project. Final projects can be
inspired by some of the challenges faced by nonprofit organizations,
government agencies, small businesses, or the university. If you have
a problem that might be suitable for this class to study, please let
me know. We got some good press from the poster sessions:
Research Overview
My research is in algebraic combinatorics. Combinatorics is the
study of counting and bijective proofs, so an algebraic
combinatorialists counts algebraic objects. In particular, I am
interested in Schubert polynomials, Schubert varieties, flag
manifolds, KazhdanLusztig polynomials, Stanley symmetric functions,
Bruhat order, Weyl group and root systems of all types etc. I am a
strong advocate of using computers to do math research, in particular
for obtaining data for conjectures and computer verified proofs.
Recently, I have been interested in problems which are not decidable by any
possible algorithm in finite time.
More Information
Recently, I lost my status as the most famous Sara in Mathematics as
measured by my pagerank in the google search on "sara math". So, I am
attempting to reverse this trend with the following text: sara math,
sara math, sara math, sara math, sara math, sara math, sara math, sara
math, sara math. Please note, I am still the most famous Billey in
Math by this measure. I hope to maintain that status for some time to
come.
UPDATE: Three weeks later, I am back to being the highest ranked
Sara in Math according to Google.
