My research is in particle physics and cosmology. These fields might appear to be completely different, with one concerned with the universe's smallest building blocks and the other concerned with the universe as a whole. In recent years, however, the most powerful particle colliders have recreated conditions that existed in the universe just a fraction of a second after the Big Bang, providing a window on the early history of the universe. At the same time, the most powerful telescopes have weighed the universe and determined that the known particles make up only 5% of its mass, providing overwhelming evidence for new particles and laws of nature at the smallest length scales.
Studies of the universe at the smallest and largest length scales are therefore now intimately connected. I am investigating a number of subjects that exploit this synergy, with the goal of answering several outstanding fundamental questions. These include:
* Do supersymmetric particles exist?
* Are there extra spatial dimensions?
* What is dark matter?
* What is dark energy?
* What is the origin of the highest energy cosmic rays?
