MIT Department of Mathematics

I am a fifth year graduate student in the mathematics department at MIT. I am primarily interested in representation theory, the study of abstract mathematical symmetries. Most of my research is inspired by the Orbit Method, a mysterious and conjectural correspondence between coadjoint orbits (geometric objects related to classical mechanics) and unitary representations (analytic objects related to quantum mechanics). I am working under the supervision of David Vogan. Next year, I will be a Titchmarsh research fellow at Oxford Universtiy.
My CV is here. My research statement is here.
Gluing Sheaves Over Codimension 1 (joint with James Tao, link to PDF )
Let X be a smooth variety which decmposes under the action of an algebraic group G into an open orbit U and a closed orbit Z of codimension 1. We provide an algebraic description of the category of Gequivariant vector bundles on X. The resulting theory has numerous applications to the representation theory of real reductive groups.
Unipotent Representations Attached to the Principal Nilpotent Orbit (arXiv)
I construct and classify the (special) unipotent representations of a real reductive group attached to the principal nilpotent orbit.
Upper Triangularity for Unipotent Representations (arXiv)
There is evidence to suggest that every unitary representation (of a real reductive group) can be built (through several types of induction) from unipotent representations. I show that under favorable conditions, every unipotent representation can be built (through a more general kind of induction) from a smaller set of representations, namely unipotent representations attached to birationally rigid orbits.
Unipotent Representations and Microlocalization (arXiv)
I develop a theory of microlocalization for HarishChandra modules, inspired by the work of Ivan Losev on primitive ideals. This theory gives rise to a nice formula for the Ktypes of a unipotent representation attached to a nilpotent orbit with small boundary, proving (in a large family of cases) an old conjecture of Vogan.
Natural Operations in Differential Geometry (masters thesis, link to PDF)
What do the Lie bracket (of vector fields), the wedge product (of differential forms), and the exterior derivative (of differential forms) have in common? They are all natural operations (i.e. independent of local coordinates). In this thesis, I use the representation theory of GL(n) to classify all such operations on differential forms and alternating multi vector fields.
Decoding Roger Williams: The Lost Essay of Rhode Island's Founding Father (link to Amazon)
As a college student, I used statistical techniques to decipher an unpublished essay of Rhode Island's founding father. In this book, the text of this essay is revealed and placed in historical context.
