Curriculum Vitae on gitlab
I am currently a graduate student at Caltech, started August 2014.
Worked as a commissioner of the Advanced LIGO Hanford Gravitational-Wave Observatory intermittently for a total of two years.
Focused on modeling laser frequency and intensity control systems' noise masking the gravitational-wave signal.
Measured and simulated interferometer transfer functions to infer interferometric parameters, including 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.
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.
Mode matching, polarization, mode cleaning, laser intensity control, laser frequency control, cavity temperature control
