Research

I have a range of research interests in physical and theoretical cosmology, mostly centred on the issue of testing the cosmological model and the origin of cosmic structure with cosmological observations. A particular focus is the the origin, interpretation, and measurement of temperature anisotropies and polarization in the CMB. I am a Core Team member of the Planck High-Frequency Instrument and a member of the Simons Observatory with particular interests in lensing of the CMB, constraining the key cosmological parameters and searching for B-mode polarization induced by gravitational waves from the early universe.
