I am a theoretical physicist, and my research is in cosmology, astrophysics, and elementary-particle theory.  My primary  research interests vary from year to year, but my main focus has been on particle dark matter, inflation and the cosmic microwave background, and cosmic acceleration.  I have also worked on neutrino and nuclear physics and astrophysics, large-scale-structure and galaxy formation, intrinsic galaxy alignments and gravitational lensing, gravitational waves, phase transitions in the early Universe, alternative-gravity theories, the first stars and the epoch of reionization, and a bit in stellar and high-energy astrophysics.
