I am a graduate student in the Harvard Department of Mathematics, working with Mike Hopkins. My interests are in homotopy theory, category theory, algebraic geometry, and the intersection of these. My recent projects have focused on developing a theory of localization of types in homotopy type theory (analogous to that for spaces, see "Research" below) and understanding certain aspects of weak equivalences in the Joyal model structure on simplicial sets (ongoing).

I did my undergraduate at the University of Massachusetts Amherst, where I wrote an honors thesis in algebraic geometry with Jenia Tevelev. Before UMass, I was at Cape Cod Community College, where I was into physics and student journalism. After UMass, I did Part III at Cambridge.

I am involved with monthly women in math lunches at Harvard, now organized by Lucy Yang and Gwyneth Moreland. These provide informal opportunities for women in the community to get to know each other. Please feel free to e-mail me if you would like to know more!

I am an organizer for the MIT Talbot Workshop, along with Calista Bernard, Yajit Jain, and Sean Pohorence. If you have questions or suggestions about Talbot, please contact me or e-mail talbotworkshop AT gmail DOT com.

Research
  • Localization in Homotopy Type Theory, with J. Daniel Christensen, Egbert Rijke, and Luis Scoccola. To appear in Higher Structures.
  • Effective divisors on moduli spaces of rational curves with marked points. Michigan Math. J. 65 (2016), no. 2, 251--285. My undergrad thesis; I also created a related database of spherical hypertree divisors generated using Macaulay2.

  • Teaching
  • In summer 2019 I am teaching a tutorial on Knot Invariants and Categorification, with co-instructor Joshua Wang. .
  • In summer 2018 I taught a tutorial on Category Theory.
  • In spring 2018 I taught Math 21b (Linear Algebra and Differential Equations) at Harvard.

  • Notes and expositions
  • A more expository slide talk on Homotopy Type Theory and the main results of Localization in homotopy type theory. Given at the Women in Homotopy Theory and AG conference in Berlin (March 2019).
