Biography

Professor Savransky received his PhD in Mechanical and Aerospace Engineering from Princeton University, where he was a member of the High Contrast Imaging Laboratory. After completing his doctorate in 2011, he became a postdoctoral fellow at the Lawrence Livermore National Laboratory where he assisted in the integration and testing of the Gemini Planet Imager and participated in the planning of the Gemini Planet Imager Exoplanet Survey.

Research Interests

Professor Savransky’s research is comprised of a variety of problems related to the detection and characterization of extrasolar planets. These include investigations of advanced control and estimation for active wavefront control systems; computer vision and machine learning applications for automated optical system alignment and astronomical image post-processing; optimal scheduling for autonomous space observatories and ground-based surveys; and statistical analysis of large astronomical surveys.
