I am a theoretical cosmologist working at the interface between theory and data. I develop techniques that maximize the scientific return from cosmological surveys, particularly of the cosmic microwave background, and I work out what the resulting measurements imply for fundamental physics, from the properties of neutrinos and the dark sector to the physics of the early universe and gravitational waves.

Research

The inferred sum of neutrino masses, with negative values allowed: CMB data alone and CMB with DESI both prefer a value below zero, below the minimum allowed by neutrino oscillations

Neutrinos and the Dark Sector

Neutrino mass, light relics, big bang nucleosynthesis, and the dark sector.

Enhancing the Value of CMB Surveys

Delensing, new probes of cosmic structure, and machine learning tools.

The gravitational-wave landscape from 10^-19 to 10^4 hertz, with the frequency ranges covered by CMB B modes, pulsar timing arrays, CMB time-dependent deflection, a gravitational-wave timing array, LISA, and LIGO-Virgo-KAGRA

Gravitational Waves Across Frequencies

Primordial B modes, pulsar timing arrays, and new searches with the CMB and lensed fast radio bursts.
