I study dark matter, the invisible material that makes up 85% of all matter in the universe. My research combines techniques from particle physics, cosmology, and black hole physics to extract new hints about what dark matter is and how it behaves.

Understanding the nature of dark matter gives us crucial pieces to the puzzle of our universe: what was the universe like just after the big bang, and how did it form into the cosmos we see today? What particles and symmetries have we yet to discover? And why is there matter at all? The search for dark matter bears on all these questions and more.
