Hi there! I'm a theoretical physicist--I work on topics related to general relativity. I currently teach classes at St. Edward's University and work as an affiliate researcher at the University of Texas at Austin. Here's my cv.


Physics

Notes:

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.

Codes

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.
