Howdy! I am a former UT graduate student, now a research affiliate in the physics department working with Prof. Richard Matzner in the relativity group. Here's my cv.

Research Interests

My research is a mixture of theoretical and numerical work in General Relativity. In particular, I work on topics involving variational principles in General Relativity (with a focus on boundary terms), the 3+1 formalism and the Post-Minkowskian approximation. My dissertation concerns spatial boundary conditions in the path integral formulation of quantum General Relativity.


My Notes:

The Poor Man's Introduction to Tensors - These are my notes on tensors--These are intended to serve as an introduction to tensor calculus (in Euclidean space) accessible to those with a basic knowledge of linear algebra and vector calculus. (Updated September 2017)
