- Assistant Professor at SLU 2023-
- NSF Postdoc and Chauvenet Postdoc at WashU 2019-23
- PhD Yale 2019
- BA UC Berkeley 2013
- Full CV
- SLU Geometry and Topology Seminar
- ForALL, the SLU math department's semesterly math magazine
- Directly related to my research:
- Slides from a lightning talk about Endperiodic maps, splitting sequences, and branched surfaces (joint with Tsang) at Yair Minsky's 60th birthday conference in May 2023.
- A poster I made about the paper Endperiodic maps via pseudo-Anosov flows (joint with Minsky and Taylor). This was for a poster session at the workshop "Flexibility and Rigidity in Dynamical Systems" at the Simons Center in March 2022.
- NCNGT 2021 talk: "Limits of dilatations and depth one foliations." Video and slides.
- Slides from a talk I gave about the papers "Veering triangulations and the Thurston norm: homology to isotopy" and "A polynomial invariant of veering triangulations."
- Tangentially related to my research:
- I coörganized the St. Louis Topology Conference (17-19 May 2024). The theme was foliations and flows in 3-manifolds. I designed the conference poster and t-shirt.
- Thoughts on and images from my notebook
Written for the Fall 2024 issue of ForALL. - Seifert surfaces and genera of knots
Originally these were notes for an expository talk given at the Summer Undergraduate Mathematics Research at Yale (SUMRY) program in 2014, and later I adapted them to appear in ForALL in Fall 2023.
