Research Interests:
perverse sheaves and the decomposition theorem,
modular representation theory, particularly from a geometric perspective, torsion in cohomology,
weights (e.g. Frobenius action and Weil conjectures or Hodge theory) and especially their interactions with perverse sheaves,
Soergel bimodules, their Hodge theory and relations to representation theory,
combinatorial models for perverse sheaves (e.g. Soergel bimodules, moment graphs, "intersection cohomology" of polytopes etc.),
algebra that looks geometric (e.g. the coinvariant algebra of H3),
categorification, diagrammatic algebra, "generators and relations",
higher categories (usually stopping at 2 or 3!), especially monoidal categories and their module categories,
Kazhdan-Lusztig theory and its modular versions (p-canonical basis etc.)
braid group actions and link homology,
microlocal approaches to perverse sheaves, characteristic cycles.
