I work primarily in representation theory, leaning towards topological/geometric approaches.

I am not affiliated with any institution (euphemism for unemployed).

Here is my CV.

**Preprints**

- Some geometric facets of the Langlands correspondence for real groups,

to appear in Bulletin of the L.M.S. - A remark on braid group actions on coherent sheaves,

**Miscellaneous articles**

- Graded tensoring and crystals
- On Hall-Littlewood polynomials
- On the geometric Hecke algebra,

Enveloping Algebras and Geometric Representation theory, Oberwolfach Reports**9**, Issue 1 (2012). - A note on Hecke patterns in Category O
- A remark on some bases in the Hecke algebra
- Derived equivalences and category O,

PhD thesis, UW-Madison, 2011.

**Incomplete/scratch work**

- Equivariant nearby cycles [unstable]
- Misc. discussion around smooth base change and induction equivalence
- Discussion around smooth morphisms and the equivariant derived category

This is related to the equivariant part of the preprint `On Euler-Poincare characteristics' above. - Discussion around the cohomology of the complement of a normal crossings divisor
- Notes on motivic models for category O
- Some geometric facets of the Langlands correspondence for real groups

This is an ugly version of its namesake above. The primary difference is that appropriate changes (technical and linguistic) are made so that the arguments work both in the setting of mixed Hodge modules and mixed l-adic sheaves. There are some interesting questions (related to `Frobenius semisimplicity') that arise in the l-adic setting. There is no discussion of convolution, the Hecke algebra, or formality in this version. - Projective functors and free pro-unipotent sheaves
- Computing extensions between sheaves (a la Beilinson-Ginzburg-Soergel)
