Summary of Research

I investigate questions of how spacetime evolves and interacts with energy by creating and testing current models that examine the fundamental physics which is the foundation of our Universe. I utilize computational simulations of various theoretical models to test these theories and generate predictions for the formation of the Universe. This includes a wide variety of topics, such as approaches to dark energy and dark matter, probing beyond Einstein's theory of gravity, and inflation and its problems.
