Objective Design and build next generation autonomous control solutions that expand our technical reach.

Profile I have enjoyed the past six years at Lockheed Martin as a guidance navigation and control (GNC) engineer. I have developed guidance and control algorithms, 6DOF simulations, visualizations, and integration solutions for the F-35 simulator, High Altitude Airship, VLA, and LRASM missile projects.
