I am a full-time lecturer at Cal Poly San Luis Obispo. From 2024-2026, I was an RTG Postdoctoral Scholar at the University of Oregon working under the supervision of Benjamin Young. From 2021-2024, I was a Krener Assistant Professor at University of California, Davis under the supervision of Fu Liu. Before this, I got a PhD in Mathematics at Brown University, advised by Caroline Klivans.

Here's me at the Pontificia Universidad Javeriana in Bogotá, Colombia for the Encuentro Colombiano de Combinatoria (ECCO) in July 2022.
I study algebraic, geometric, topological, and dynamical combinatorics. A few of my favorite topics are chip-firing, matroid theory, and discrete geometry. More generally, I tend to enjoy any project where I can play around with concrete examples to search for hidden structure. Thankfully, these kinds of projects are plentiful in combinatorics!
When doing research, I like to seek a compelling story to help explain a curious phenomenon. When a result feels neither obvious nor arbitrary, I usually take that as a sign that there is more to explore.
For particularly intriguing phenomena, I find it helpful both for presentations and my own understanding to design animations about the material. The first research animation I made is below, and you can find others in the visuals tab.
Here is an animation that I made to show off a tiling in my thesis. For more animations, see the "Presentation Materials" tab.
I am married to the amazing statstician Julia Schedler!
One of my favorite hobbies is playing, collecting, and reading about board games. A well written board game instruction manual has many of the same characteristics as a well written research paper (such as clear logic, judicious structure, and plenty of examples). I feel that learning new games has been great practice for learning new mathematics, and teaching rules to others has been great practice for lecturing!
I also love participating in rec league/ intramural sports whenever I can, especially basketball!
