We are investigating and developing the theory of elementary particles and their interactions. I am especially interested in searching for (and ultimately finding!) signals of new physics beyond our standard model. These are exciting times to pursue this endeavor: The Large Hadron Collider at CERN is providing us daily with billions of bytes of fresh data to explore. Currently, I am focusing on two candidates which I think might help us to discover new physics: top-quarks, the heaviest elementary particles we have found so far; and very weakly interacting particles we haven't found yet, but which are good candidates for dark matter.

Whether you are one of my colleagues or just as curious about knowing the fundamental laws of Nature as we are, I invite you to check out my publications.
