Research interests

  • Cosmology
  • Nuclear and particle astrophysics
  • Neutrino physics

My research interests in cosmology involve exploring the connections between fundamental physics and the structure and evolution of the universe. Of particular interest to me are theories attempting to reconcile neutrino- and other Beyond-Standard-Model physics with ever-improving constraints on cosmic microwave background (CMB), nucleosynthesis, dark matter and structure formation

I am also interested in the role of neutrinos in the dynamics and nucleosynthesis in compact objects and high energy astrophysical processes, e.g., calculations of neutrino flavor and spin evolution in supernovae
