Sandeep Singh


Professor Sandeep Singh joined the Mechanical, Aerospace and Nuclear Engineering department at Rensselaer Polytechnic Institute as a tenure-track Assistant Professor in July 2022. He received his Ph.D. from Texas A&M University in 2022 where his thesis focused on leveraging manifolds and manifold-analogues to generate efficient, ephemeris-driven, piecewise optimal trajectories with eclipse consciousness. Professor Singh was also a graduate fellow during Summer 2020 at Jet Propulsion Laboratory, California Institute of Technology where he spent the previous summer as an intern. During his doctoral studies, he was awarded several university fellowships as well as the John V. Breakwell Student Award conferred by the American Astronautical Society. Prior to starting his doctoral studies, he was employed as a Scientist at Space Applications Center, Indian Space Research Organization where he served as Program Manager for Mechanical Design of the ASTROSAT mission. He also supported efforts for optical assembly design and was responsible for developing innovative, low-risk, space-qualification testing methods like the Force Limited Vibration Testing for fragile remote sensing payloads. He actively serves as a referee for several international journals and conferences and has published several journal articles and conference papers.
