• Technical Lead for SciSat-1 Attitude Determination and Control Subsystem• Systems Lead for GyroWheel product development. The GyroWheel is a reaction wheel whose rotor is mounted on a flexure so that torques can be applied in 3 axes with a single mechanism and so that it can be used to measure the cross axis rate.
