I am an observational astronomer and astronomical instrumentalist at the NASA Jet Propulsion Laboratory in Pasadena, CA. I am interested in developing new instrumentation and techniques for a variety of astronomical science applications, with a particular focus on extra-solar planet detection and characterization. Scientifically, I work on pushing the limits of extra-solar planet detection using both ground and space-based astronomical facilities. Instrumentally, I develop new optical and mechanical instrumentation for high resolution astronomical spectrometers, designed from the ground up to search for planets orbiting nearby stars.My work has spanned a variety of instrumentation and science topics, each of which represents a high-impact contribution to the field of precision Doppler radial velocity (RV) surveys for exoplanet discovery. I am an integral member of several field-leading exoplanet science and instrumentation teams, having played a significant role in the development of multiple precision exoplanet detection systems and surveys in the past decade. My experience spans a range of technological (optical design, optical fiber systems, calibration technologies), methodological (data reduction pipelines, Doppler analysis tools), and scientific (planet detection, stellar activity characterization) disciplines. I have played a central role in the design, delivery, commissioning, and science output of three facility-class astronomical spectrometers, two of which are fully operational and have amassed a wealth of interesting science discoveries, and the third currently mid-commissioning. Most recently, I serve as the Instrument Scientist and Co-Project Scientist for the Keck Planet Finder (KPF), a premier Doppler exoplanet facility for Keck Observatory that is currently commissioning at Keck.I have many years of experience with high precision optical instrumentation, particularly in the context of visible and infrared imaging and spectroscopic systems. My dissertation work focused on developing optical fiber-fed high-resolution spectrographs. I have developed a variety of optical fiber-based sensors and devices to improve spectroscopic measurement sensitivity of astronomical spectrographs to unprecedented levels, as these instruments are designed to measure frequencies of spectral features to precisions better than a part per billion. These devices include: stabilized fiber-based wavelength calibration sources (in both the visible and near-infrared), optical fiber image scramblers, and laser speckle-suppression systems.
Listed skills include Physics, Data Analysis, Latex, Spectroscopy, and 13 others.
