Nicholas Galitzki focuses on experimental cosmology, astrophysical instrumentation, data analysis, polarimetry, cosmic microwave background, interstellar medium, dust, cryogenics and balloon-borne telescopes. An experimental cosmologist with a focus on detecting primordial gravitational waves through observations of the cosmic microwave background (CMB), his research encompasses the design, implementation, and characterization of cryogenic cameras for millimeter and submillimeter observations, as well as data analysis from on-sky observations. He is actively involved with the Simons Observatory, particularly with the small aperture telescopes aimed at observing the polarized CMB signal at large angular scales. To enhance the capabilities of these instruments and pursue ambitious scientific goals like cosmic birefringence, he is also part of the Hover-Cal project, which employs drones for calibration. Both projects are conducted at a site in Chile’s Atacama Desert, situated at an altitude of 5,200 meters.
