I am a PhD candidate in math arrived in 2017 at Stony Brook University. I am interested in topology, especially of manifolds and algebraic varieties. My advisor is Dennis Sullivan.

  • Research

  • Almost complex manifolds with total Betti number three (arXiv preprint).
  • (with A. Milivojević) Infinite symmetric products of rational algebras and spaces (to appear in Comptes Rendus Mathématique)

  • Notes

  • Topological resolution of singularities for talks I gave at City University of New York Graduate Center Topology, Geometry and Physics seminar in November 2019, at University of Science and Technology of China in December 2019, and at University of Pennsylvenia defomation theory seminar in Feburary 2020.
  • Elliptic cohomology and elliptic genera for a series of talks I gave at student topology seminar in spring 2020, Stony Brook University.
  • Steenrod and Adams operations from easy algebra This is a detailed note attempting to interprete Jack Morava's point that "the dual Steenrod algebra is the automorphism group of the additive group". In particular, we solve the equations f(x+y)=f(x)+f(y) and f(x+y+xy)=f(x)+f(y)+f(x)f(y) by formal power series with coefficients in the field of p elements, and then relate the space of solutions to Steenrod and Adams operations respectively.
