About Me:

I am a Postdoctoral Researcher in the Department of Mathematics at Louisiana State University, working with Pramod Achar. I recieved my Ph.D. from the University of Georgia in Spring 2016 under Daniel Nakano. Here is my CV.

My research is in representation theory, with an emphasis on representations of algebraic groups in positive characteristic, and their connections with geometry.



  1. (with P. Achar, S. Riche) Integral exotic sheaves and the modular Lusztig-Vogan bijection (in preparation).

  2. The smoothness of integral nilpotent centralizers (in preparation).

  3. (with P. Achar) Calculations with graded perverse-coherent sheaves (submitted).

  4. The Loewy structure of modules in a singular block of $\mathsf{Rep}(G_1T)$ for $SL_{n+1}(\mathbb{k})$ (submitted).


  1. (with P. Achar, S. Riche) On the Humphreys conjecture on support varieties of tilting modules (to appear, Transform. Groups).

  2. On support varieties and the Humphreys conjecuture in type $A$, Adv. Math. 329 (2018), 392-421.

  3. (with D. Nakano, P. Sobaje) On the Existence of Mock Injective Modules for Algebraic Groups, Bull. Lond. Math. Soc. 49 (2017), 806-817.

  4. Support varieties of line bundle cohomology groups for $G=SL_3(k)$, J. Algebra 448 (2016), 127-173.
