Dr. Sumita Nandi is a senior engineer supporting Stardust since joining the Guidance, Navigation and Control Section in early 2005. At JPL since 1991, she has implemented various signal processing, physical modeling and least-squares estimation algorithms for applications including GPS, orbit determination and infrared remote sensing. A highlight of her efforts at JPL was developing the real-time software to control the high precision Ka-band ranging system for the GRACE mission. Her more recent work has focused on implementation and support for the DSN's spacecraft VLBI capability.

Dr. Nandi received a B.A. degree in physics from University of Chicago in 1985 and an M.S. and Ph.D. in High Energy Physics from Cornell University in 1987 and 1991, respectively.
