Research Summary

I am interested in using theory to connect the earliest moments in our Universe’s history with observations and experiments today, with the goal of learning about the fundamental constituents of our universe. The big problems that I work on include the nature of dark matter (a key and so-far unidentified component that makes up 84% of matter in our universe!); the origin of neutrino masses (they are supposed to be massless within the Standard Model!); and the excess of matter over antimatter in our universe (good for us, but they were supposed to have annihilated early on!). Solutions to these problems require the introduction of physics beyond the Standard Models of particle physics and cosmology, so I am generally interested in searching for this "new'' physics.

I am mainly a theoretical physicist, but a large component of my work involves understanding how various models for beyond Standard Model physics
can be constrained by existing data spanning particle physics, cosmology, astrophysics and precision laboratory experiments. I often develop new search strategies for existing experiments, or propose new ones.
