My current research is on the motivic homotopy theory of Stiefel varieties GL(n)/GL(n-r) with applications to algebraic vector bundles. The main project of my PhD thesis is to construct sections of a canonical map between Stiefel varieties, or show that no such section exists, using methods from motivic homotopy theory. The existence (or nonexistence) of a section is related to splitting free summands from stably free modules.
Some related projects are calculating the stable homotopy groups of motivic spheres and establishing a motivic stable splitting of the Stiefel varieties, analogous to this paper.
I am also interested in classifying spaces in motivic homotopy theory and their approximations.

My master's thesis focused on using homotopical approximations to the classifying space BPGL(2, C) to bound the minimal number of generators of a degree 2 Azumaya algebra.
