Welcome to my home page. I am a professor in the math department 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 Indiana University-Bloomington, a postdoc at MSRI (fall 2004), Michigan (2001-2004) and the University of Washington (1999-2001), went to grad school at MIT (1995-1999), and undergrad at Harvard (1991-1995). I spent fall 2010 visiting Cornell thanks to the very generous support of the Ruth Michler Prize of the Association for Women in Mathematics (AWM). Richard Stanley was my Ph.D. advisor, and Phil Hanlon was my NSF postdoc sponsoring scientist at Michigan; Persi Diaconis was my undergraduate advisor.

Research:

Here are my publications, 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 computer science. I'm especially interested in combinatorial methods for studying topological structure, often with algebraic applications in mind.

Current Ph.D.students: Stephen Lacina (6th year).

Past Ph.D. students: Molly Lynch, NCSU 2019 Ph.D., tenure track assistant professor at Hollins University. Grace Stadnyk, NCSU 2019 Ph.D., tenure track assistant professor at Furman University. Chetak Hossan, NCSU 2019 Ph.D. (with coadvisor Nathan Reading), 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.

Editorial boards and advisory boards: Forum of Mathematics PI (editorial board, March 2019--present); Forum of Mathematics SIGMA (editorial board, March 2019--present); Springer Graduate Texts in Mathematics (managing editor, January 2023--present; advisory board member, April 2019--present), Proceedings of the AMS (combinatorics editor, February 2014--January 2022) and SIAM Journal on Discrete Mathematics (editorial board, January 2011--December 2016).

Some helpful organizations: NSF, AMS, AWM, MAA and SIAM.
