About

I am a fifth year PhD student at UT. My advisor is Andrew Blumberg. I can be contacted at [username, see URL]@math.utexas.edu.

Seminars

In Fall 2017, I organized Arithmetic Geometry, Homotopy, And String Theory (AGHAST).

Research

I am interested in algebraic \(K\)-theory, particularly trace methods; equivariant stable homotopy theory; chromatic homotopy theory; and higher category theory. I am frequently interested in how these interact with arithmetic geometry, especially the subjects of \(p\)-divisible groups and crystalline cohomology.

Please enjoy the following animation of Waldhausen's \(S_\bullet\) construction (move your cursor over the entries in the diagram on the left). (If you started on a different tab, you may need to refresh the page for this to work.)
