Research Description

My research interests lie at the intersection between the universe's workings on its largest and smallest scales.  Recent work includes:(1) Observational cosmology with the cosmic microwave background, particularly the search for evidence of primordial gravitational waves with balloon-borne (SPIDER) and terrestrial (the BICEP/KeckArray program) instruments.(2) Searches for the interactions of particle dark matter in terrestrial detectors.(3) Development of advanced instrumentation for astrophysics and fundamental physics, often involving detectors operated at sub-Kelvin temperatures.My work involves both instrumentation development and data analysis.
