I am a graduate student at Harvard university and my advisor is Mike Hopkins . I am applying for postdoc positions starting fall 2017.

My current research is in algebraic topology. More precisely, I am intrigued by the interplay and differences between characteristic zero and positive characteristic algebraic phenomena, and I think these manifest richly in homotopy theory.

Here is my CV.


  • The Equivariant Symmetric Power Filtration and the Dual Steenrod Algebra (thesis), in preparation. For G=Z/p, I use the symmetric powers of the G-equivariant sphere spectrum to compute a dual Steenrod algebra-esque decomposition of HF_p \sm HF_p (F_p denoting the constant Mackey functor). For now, here is a brief outline of my thesis. I hope to have a preliminary draft ready and on this webpage by the end of January.
  • Achievable Sets in Z^n (2012) paper, journal link . I wrote this paper as an undergraduate at the 2010 Duluth REU. A seemingly simple question in number theory led me to my first foray into topology.
