About me

I’m a graduate student at the Harvard math department. You can email me at .

I’m interested in homotopy theory, higher category theory, derived algebraic geometry and combinatorics.

Expository writing

Expository papers (PDFs):


In the spring of 2012, I taught a tutorial about the fundamental groupoid called Groupoids in Topology.

For a combined precalculus/calculus course called Math Ma, I wrote a couple of interactive webpages using the brilliant JXSGraph library:

  1. This an excellent program requirement: a chance to make a fool of yourself in writing by producing an exposition of a topic outside your field of expertise in a limited amount of time. I loved it! All math departments should have this.

  2. Separating them into the three topics named is left as an exercise for the reader.

  3. Possibly not the standard name for workers in this field.

  4. The people on this list do lots of other stuff too.
