Moreover, he is visiting Professorships at Université du Maine, Le Mans, France; Université de Savoie, France; Polytechnic University – Vietnam LCZ696 in vivo National University in HoChiMinh City, Vietnam; and Can Tho University, Vietnam. He received his Bachelor of Chemistry degree from the Faculty of Sciences, Saigon University, Vietnam, in 1971 and then received his Master of Science in Organic Physical Chemistry from the Faculty of Sciences, Saigon University in 1972. He

graduated with a Ph.D. degree from the University of HCM City in 1992. He was the Dean of the Faculty of Chemistry, University of Science-Vietnam National click here University in HoChiMinh City, Vietnam, from 2002 to 2007. His research interests include modification of natural polymers (rubber, chitosan, etc.), natural or synthetic polymer-controlled degradation, synthesis of systems containing free and/or linked plant growth stimulator molecules in rubber/polymer matrix, living polymers, polymer blends, composite materials, nanocomposites, and graphene.
