I am at the University of Illinois Urbana-Champaign Department of Mathematics as an NSF postdoctoral fellow (DMS-1401591). Tandy Warnow is my sponsoring scientist for this grant. I am also a J.L. Doob Research Assistant Professor. My professional mentor in the Department of Mathematics is Bruce Reznick.
Office: 165 Altgeld Hall
Office Hours Spring 2017: By Appointment. Appointment requests are always welcome!

This semester I am visiting CIMAT during Spring 2017 to do research with Abraham Martín del Campo Sanchéz. My office at CIMAT is K304. Please communicate with me via email. I will be making several trips to the U.S. during Spring 2017, so email me if you want to schedule a meeting at UIUC, or if you are at CIMAT and wish to meet.
My areas of research interest are mathematical phylogenetics, geometric combinatorics, and algebraic statistics.

Speaking at the "Algebraic and Combinatorial Phylogenetics" Workshop June 26-30, 2017, part of the Mediterranean Month in Phylogenetics, June 12th-July 10th, 2017 in Barcelona and Porquerolles, sponsored by BGS Math.
Visiting Scholarship at the University of Tasmania Fall 2017. This will coincide with the theoretical phylogenetics conference Phylomania.
Here is a flyer advertising the graduate class "Polyhedra in the Wild" that I taught in Spring 2016, and the main course page.
I also supervised a project in the Illinois Geometry Lab titled "Discrete Morse Theory, Vector Fields, and Materials Science" that is continuing in Fall 2016.
In 2014, I received my Ph.D. from the Mathematics department at North Carolina State University under the supervision of Patricia Hersh and Seth Sullivant.
In 2009, I received my B.S. in Mathematics at the University of Washington, Seattle. My undergraduate thesis supervisor was Sara Billey.
In 2006, I received my A.A. from Seattle Central College, formerly known as Seattle Central Community College.
I am organizing a special session at the SIAM Applied Algebraic Geometry Conference in Atlanta, July 31-August 4, 2017 at Georgia Tech. The minisymposium is entitled "Algebraic and Topological Biology." Please see this wiki for an overview of minisymposia at the conference. Note, early career travel grants had a deadline of 2/3/17 which has been extended to 2/24/17.
Talks and Events : talks, activities and events I've organized, and other conferences and workshops I've attended.
