Dr Guyon has been developing and validating in the laboratory innovative techniques for detecting and characterizing Extrasolar planets. Dr Guyon's research includes coronagraphy, wavefront sensing techniques for Adaptive Optics, and astrometry. Dr Guyon developped the Phase-Induced Amplitude Apodization (PIAA) coronagraph, a highly efficient optical device to mask light from a star while preserving light from planets around it.
Dr Guyon is currently leading the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) group at the Subaru Telescope to use these new techniques on the Subaru telescope for exoplanet detection and characterization. Dr Guyon also works for the University of Arizona, where he is developing high contrast imaging techniques for current and future ground and space-based telescopes.
Dr Guyon was awarded the 2006 Presidential Early Career Award for Scientists and Engineers (PECASE) by Office of the President of the United States, and the 2012 MacArthur fellowship.
