My research is primarily targeted at gravitational wave detection on the ground (LIGO) and in space (LISA). As a member of the LIGO Scientific Collaboration, I study the optical characteristics of the Advanced LIGO detectors using frequency domain modal simulations in order to improve the reliability and sensitivity of these instruments. I also work on experimental R&D for future technologies for upgrades to the LIGO detectors, and for a new generation of ground-based gravitational wave detectors. Current R&D projects include using electro-optic beam deflectors to produce interferometric alignment sensing signals without the need for quadrant photodetectors, and the use of higher-order Hermite-Gauss beams for precision interferometry.
