PhD in Experimental Gravity from
Curriculum Vitae on gitlab
I am currently a postdoc at LIGO Hanford Observatory, starting in February 2021.
I graduated from Caltech with a PhD in experimental astrophysics, with a focus on calibration uncertainty and interferometer controls.
As a grad student I worked as a commissioner at LIGO intermittently for a total of two years.
I focused on modeling laser frequency and intensity control systems' noise masking the gravitational-wave signal,
measured and simulated interferometer transfer functions to infer the resonant arm power,
measured and simulated the differential arm (DARM) degree of freedom for comparison between the expected response to gravitational-waves and reality,
and created the advanced-detector era interferometric calibration uncertainty budget pipeline.
Worked in the Caltech optical coatings thermal noise lab for testing aluminum gallium arsinide (AlGaAs) optics coatings.
Locked two lasers' frequencies to two Fabry-Perot cavity lengths with the goal of measuring cavity mirror coatings Brownian noise.
