About

Greg Ching is an observational astronomer and instrumentation specialist whose work centers on developing and deploying cutting-edge adaptive optics (AO) systems that push the limits of ground-based imaging. His primary research areas include high-angular-resolution astronomy, robotic telescope operations, and the engineering of real-time wavefront correction for both visible and near-infrared wavelengths. Ching’s most significant contribution is his leadership in the commissioning of Robo-AO-2, a next-generation automated laser AO system installed on the University of Hawaii 2.2-meter telescope on Maunakea in 2023. This system was engineered to deliver robotic, diffraction-limited observations at an unprecedented scale, dramatically increasing the number of high-resolution images astronomers can obtain each night. By enabling rapid, automated AO correction, Ching’s work directly impacts studies of binary star systems, solar system objects, and crowded stellar fields. While his most-cited paper currently holds 1 citation, the Robo-AO-2 project represents a major technical achievement in the field, promising to transform how large-scale AO surveys are conducted. Ching’s dedication to advancing instrumentation ensures that ground-based telescopes can continue to rival space-based observatories in image sharpness and scientific output.
