Research Interests

My interests are in the formation and application of cold and ultracold molecules.

  • Stark deceleration of cold polar molecules
  • Buffer gas cooling and magnetic guiding of molecules
  • Sympathetic cooling of cold molecules with ultracold atoms
  • Using cold, polar molecules to measure the electric dipole moment of the electron
  • Using ultracold polar molecules to study the physics of highly correlated quantum matter
