Recently we have prototyped electronic systems and effects, conducted hardware-in-the-loop testing of tactically relevant payloads with surrogate threat systems, developed RF subsystems for satellites, and analyzed spacecraft mission dynamics, environments, and resiliency. Experience developing engineering and scientific analyses, simulations in MATLAB (core, Simulink, and Aerospace Toolbox), COMSOL Multiphysics, Ansys Systems/Satellite Tool Kit (AGI STK).
