Professional Summary

I designed/implemented numerous critical automatic servo controllers successfully for opto-mechatronics applications (i.e., Philips’ portable CD player, Samsung’s robust DVD, and ASML’s optical module) with my practical robust multi-variable control design method (DQFT) as well as other methods. In addition, I am a practical engineer/manager who can develop cost effective solutions (i.e., solar concentrator) on your critical engineering problems with many years of industrial experiences.
