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. Recently I've been thinking about algebraic K-theory, and questions about algebraicity of vector bundles. My other grad school 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, but currently on hold).

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 Lucy Yang. If you have questions or suggestions related to Talbot, contact me or e-mail talbotworkshop AT gmail DOT com.

**Teaching**

For the 2020-2021 academic year, I will be a Bok Center Pegagogy Fellow in mathematics.
In summer 2019 I taught 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.
In fall 2017, I was a graduate course assistant for math 23a (Linear algebra and real analysis I) 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).
