Upon completion of his doctorate in chemistry at The University of Tokyo in 1995 Dr. Yan joined the R&D group at Ibaraki Research Laboratory, Hitachi Chemical Industry Co. Ltd. where he carried out research works to develop sophisticated electronic components by utilizing functional polymers. After his research works on conductive polymers at Tokyo University of Science, Yamaguchi for 6 years, and on polymer gels and super water-repellent materials at Hokkaido University for 3 years, Dr. Yan joined the Laboratory of Organic Robotics at the University of Yamanashi in 2007-2011 where he is an Associate Professor. Before his above career in Japan, Dr. Yan had been educated in China, i.e., in Jilin University (1978-1982) for Bachelor of Science on polymer chemistry and in Henan Institute of Chemistry (1984-1987) for Master of Science on inorganic chemistry. Dr. Yan has completely moved back to China in 2011 as a full professor of Zhengzhou University. His research fields are conducting polymers; organic electronics; superhydrophobicity; polymer nanoparticles; hydrogels. Dr. Yan has published 13 books, 85 papers, and 38 patents (h-index: 21). Currently Dr. Yan serves as editorial board members of journals Scientific Reports, Recent Patents on Materials Science, etc.
