Below is a selection of talks I have given related to my work on theoretical cosmology:

  • Cosmology and a Massive Graviton (PDF). I discuss my and my collaborators’ work on massive gravity, its extension to bigravity, and cosmological tests thereof.
  • Aspects of Field Theory with Higher Derivatives (PDF). This talk is about my work on field theoretic aspects of scalar and scalar-tensor theories, including the galileon and Horndeski theories popularly used for cosmological purposes. I discuss non-perturbative solutions and effective field theory considerations.
