Welcome to my home page. I am a professor in the
at the University of Oregon.
Before this, I was a math faculty member for many years at
North Carolina State University and prior to that at
a postdoc at MSRI (fall 2004),
Michigan (2001-2004) and
University of Washington (1999-2001), went to grad school at
MIT (1995-1999), and undergrad at
I spent fall 2010 visiting
thanks to the very generous support of the
Prize of the
Association for Women in Mathematics
Richard Stanley was my
Ph.D. advisor, and
Phil Hanlon was my NSF postdoc sponsoring scientist at Michigan;
Persi Diaconis was my undergraduate advisor.
Here are my
talk slides and upcoming talks/conferences, and my
CV. This work
is supported by NSF grant DMS-1953931.
Research interests: combinatorics, particularly as it relates to fields like
topology, commutative algebra, representation theory and theoretical
I'm especially interested in
combinatorial methods for studying topological structure, often with
algebraic applications in mind.
students: Molly Lynch, NCSU 2019 Ph.D., now a visiting assistant professor at Hollins University. Grace Stadnyk, NCSU 2019 Ph.D., now a tenure track assistant professor at Furman University. Chetak Hossan, NCSU 2019 Ph.D. (with coadvisor Nathan Reading), now a lecturer at Texas State University. Ruth Davidson, NCSU 2014 Ph.D. (with coadvisor Seth Sullivant).
Rebecca Swanson, Indiana
University-Bloomington 2010 Ph.D., now a teaching professor at Colorado School of Mines.
Stephen Lacina (2nd year) is currently
working with me.
Editorial boards and advisory boards:
Forum of Mathematics (discrete math editor, March 2019--December 2023), Springer Graduate Texts in Mathematics (advisory board, April 2019--March 2022), Proceedings of the AMS (combinatorics editor, February 2014--January 2022) and SIAM Journal on Discrete Mathematics (January 2011--December 2016).
Fall 2020 quarter:
Spring 2020 quarter:
Math 431/531, Introduction to topology; the textbook is Topology, 2nd edition, by James Munkres.
Math 441/541 (MWF 12-12:50pm on zoom/canvas); the textbook is Linear Algebra Done Right, 3rd edition, by Sheldon Axler.
Math 607 (topological combinatorics, MWF 2-2:5pm on zoom/canvas); in lieu of a textbook we will use various survey articles and chapters, the main one being Michelle Wachs' chapter called Poset Topology: Tools and Applications that is avaiable for free at Michelle Wachs' publication list at her web site (about halfway down). We also will use Richard Stanley's chapter called Hyperplane Arrangements available for free at his web site on hyperplane arrangements.
