Astroparticle Physics and Theoretical Cosmology

My theory research encompasses dark matter, astroparticle physics, astrophysical searches for new physics, and cosmology. Theoretical physics is presently confronting exciting puzzles, including the nature of dark matter, the state of our universe prior to primordial nucleosynthesis, and the present abundance of matter as compared to antimatter. It is also interesting to consider whether the mass of the Higgs boson relative to the Planck mass, the non-zero cosmological constant, and the charge-parity symmetry of quantum chromodynamics are manifestations of more fundamental physical structures. My research seeks out new explanations for these phenomena and fashions new methods to test such explanations.
