I am a second year graduate student at Johns Hopkins. I am interested in homotopy theory, topology, category theory, and most of the related topics.

- The Diagonal of the Associahedra: A new geometric/combinatorial way to understand and construct Alexander-Whitney type maps of polytopes applied to associahedra. Joint work with Hugh Thomas, Andy Tonks and Bruno Vallette.

- Geometric Morphism: Handwritten notes for JHU category seminar on topos theory, roughly following chapter 7 of "Sheaves in Geometry and Logic" by Mac Lane and Moerdijk.
- Seminar Notes on infinity-operads as analytic monads, liveTeXed by Emily Riehl. I gave one of the talks, following section 4 of the paper, Initial Algebras and Free Monads.
- Bar-cobar and Koszul duality for algebraic operads: Notes for JHU category seminar, may contain lots of typos.
