Alexander Clark

I am a third year PhD student at the University of Melbourne.

I am currently thinking about tensor-triangular geometry, and classifying t-structures and localising subcategories of triangulated categories (with motivating examples being derived categories of schemes, algebraic spaces, algebraic stacks, and categories of motives). Previously, for my Masters thesis, I was thinking about the period-index problem from the perspective of motivic homotopy theory.
