Anand Sivaramakrishnan played a pioneering role in extreme adaptive optics coronagraphy, and was deeply involved in the first three such efforts: The Lyot Project on USAF's AEOS telescope, Project 1640 on Palomar's 200-inch, and the Gemini Planet Imager.  He also developed high resolution interferometric methods for the James Webb Space Telescope by placing a non-redundant aperture mask in one of its instruments.  He develops theoretical optics concepts and applies them to the problems of imaging planets around other stars, and the environs of supermassive black holes at the centers of Active Galactic Nuclei.  He has worked at the Observatories of the Carnegie Institution of Washington, Caltech, the American Museum of Natural History, is adjunct faculty at Stony Brook, and is based at the Space Telescope Science Institute.  He holds a patent related to coronagraphic astrometry and high-powered laser beam steering.
