After obtaining a Doctoral degree in France, I returned to teach electrical engineering at Chulalongkorn University for 28 years. I then became an Election Commissioner for 4 years and a Registrar for 2 years at the Asian Institute of Technology. Since then I have been working at Mahidol University on Peace Building especially in the Far South of Thailand. I also serve in many civil society organisations including the THNIC Foundation as its chairman.
