Jonathan Crass works on building and testing advanced astronomical instruments, particularly spectrographs and wavefront sensors used to detect and study stars and planets with extremely high precision. Much of his recent work centers on iLocater, a diffraction-limited spectrograph designed to measure tiny stellar wobbles (radial velocities) that can reveal orbiting planets or companion stars, as well as adaptive optics technology that corrects for atmospheric blurring in telescope images.
