Hello! I am an Associate Professor in Mathematics at Wake Forest University. I received my Ph.D. in mathematics from the University of Nebraska under the direction of Lucho Avramov, and did my postdoctoral work at Cornell University under the direction of Irena Peeva.

I am primarily interested in homological questions arising from commutative algebra, as well as questions in non-commutative algebra inspired by the commutative theory. I also enjoy developing software to help in experimenting with problems I am working on. See the section on software below. Below are a few neat math links, my schedule, and some of the research projects I have worked on.

**DGAlgebras**

A package for Macaulay2 to perform computations using DG algebras.

Most recent version here.

**NCAlgebra**

A package that allows Macaulay2 to interface with the noncommutative algebra package Bergman.

with Andrew Conner and Courtney Gibbons

Most recent version here with documentation file here.

Installation instructions here.

www.planetmath.org

Neat startup, especially cool because anyone can
contribute and it's open source.

mathworld.wolfram.com

Also cool, but not open source.

Not much here at this point, just dailysudoku.com's daily Sudoku math puzzle.
