My research is in algebraic K-theory – what I like
to call the Schrödinger’s cat of mathematics – when
you open the box you might see algebraic geometry, or algebraic topology.
I have worked on the K-theory of singularities, on motives and algebraic cycles, and in motivic homotopy theory. Here is a link to my CV.
