About me:
I am a Clay Research Fellow
at the University of Chicago. For winter
and spring 2019 I am based at MSRI.
My research
is primarily in algebraic topology and its interactions with algebraic geometry
and algebraic Ktheory.
I completed my PhD in mathematics in May 2017 at
Harvard University, where my advisor was Jacob Lurie.
From MayAugust 2015 and OctoberNovember 2016, I was a guest at the Hausdorff Institute of Mathematics in Bonn.
For the 20142015 academic year, I was a graduate student at the University of California at Berkeley.
Here is my
CV.
Oberwolfach Seminar:
Dustin Clausen, Lars Hesselholt, and I organize the Oberwolfach Seminar
Topological Cyclic Homology
and Arithmetic, from Oct. 2026, 2019.
The topic is algebraic Ktheory and topological cyclic homology, with a view
towards understanding Clausen's Ktheoretic approach to the Artin map.
Please see the website for more
information and how to apply.
