My research is a mixture of theoretical and numerical work in General Relativity. My theoretical work concerns topics involving variational principles in classical and quantum General Relativity (with a focus on boundary terms). I am also involved in a couple of numerical projects; I'm currently involved in the development of the PoMiN code, and the development of a GR code based on the generalized harmonic gauge formulation of the Einstein Field Equations.
The Poor Man's Introduction to Tensors - These are my notes on tensors--they serve as an introduction to tensor calculus (in Euclidean space) accessible to those with a basic knowledge of linear algebra and vector calculus. (Updated December 31st 2017)

PoMiN - This is a Post-Minkowskian N-Body code, written in C, which includes General Relativistic effects up to first order in Newton's constant G, and all orders in the speed of light c.
