Chris D'SouzaChris D’Souza received his BS and MS degrees in Aerospace Engineering at the University of Illinois, Urbana-Champaign and his Ph.D. in aerospace engineering from the University of Texas at Austin.  He began his career at the Jet Propulsion Laboratory working on the Magellan Mission to Venus.  From 1990-1996, he worked for the US Air Force Research Laboratory at Eglin AFB, focusing on optimization of trajectories, the development of optimal guidance laws for missile intercept and the very first implementation of differential GPS-aided guided munition navigation design.  He left the Air Force in 1996 and accepted a position at The Charles Stark Draper Laboratory in Cambridge and Houston specializing in autonomous rendezvous and docking, linear covariance analysis, pseudospectral methods for trajectory optimization, and optimal guidance laws for air-to-surface missiles.  Since 2005, he has been with the Johnson Space Center, first working on the Orion Navigation, Guidance and Targeting design for both rendezvous and cislunar operations.  He is currently the deputy chief of the GNC Autonomous Flight Systems Branch.  His interests are optimal guidance and targeting laws, optical navigation for rendezvous and cislunar flight, and trajectory optimization.
