He was a Visiting Scientist at MIT (USA) from 1981 to 1983 and he is a consulting professor of Xian Jiaotong University, China, 1995. He has now undertaken several research projects on the development of acoustic and optical advanced methods for measuring electric charge distribution in dielectrics. For example, in order to investigate the space charge effect in solid dielectric material, the dynamic surface charge distribution on solid dielectric materials and the electric field vector distribution in liquid insulating materials. He received the progress award from the IEE of Japan in 1996. He has also received Whitehead Memorial Award in 1999 by his pioneering work on PEA, and gave an Award Lecture in IEEE CEIDP (Conference on Electrical Insulation and Dielectric Phenomena). He further received Chen Jidan Award for his contributed works in charge measurement and quantum chemical calculation and gave a plenary speech in IEEE ICEMPE (International Conference on Electrical Materials and Power Equipment). He is a Life Fellow member of IEEE. He can be reached by email at [email protected].
