I am a fifth-year graduate student in mathematics at Harvard, advised by Curt McMullen. Previously, I was an undergraduate student at the University of Michigan.

Beginning Fall 2022, I will be a Simons Postdoctoral Fellow at the Fields Institute in Toronto. Beginning Fall 2023, I will be a Simons Instructor (research postdoc) at Stony Brook University.

My main research interests include group actions and foliations on moduli spaces, mapping class groups, and dynamics of billiards and interval exchanges.

** (1) ** Dynamics of the absolute period foliation of a stratum of holomorphic 1-forms (2021), preprint

We establish the ergodicity of the absolute period foliation of the area-1 locus of a connected stratum of holomorphic 1-forms with at least 2 distinct zeros, and we give an explicit full measure set of dense leaves. We also address the question of when two holomorphic 1-forms in a stratum, with the same absolute periods, can be connected by a path in the stratum along which the absolute periods are constant.

** (2) ** Dense real Rel flow orbits and absolute period leaves (2022), preprint

We show the existence of a dense orbit for real Rel flows on the area-1 locus of every connected component of every stratum of holomorphic 1-forms with at least 2 distinct zeros. The proof is based on a general density criterion for SL(2,R)-orbit closures, which can be verified using explicit constructions of holomorphic 1-forms with a periodic horizontal foliation. Our constructions also provide explicit examples of dense leaves of the absolute period foliation and many subfoliations of these loci.

** (3) ** Uniqueness of the Veech 14-gon, in preparation.

We show that the Veech 14-gon generates the unique algebraically primitive Teichmüller curve in its stratum component.
