Dr. Han studied chemistry for 7 years in Changchun University and Science and Technology and Jilin University, respectively, for his bachelor and master degrees. After that, he moved to Tsinghua University where he was conferred doctor degree in the field of materials science and engineering in 2004 under the supervision of Prof. Jianbao Li. His doctoral thesis focuses on the preparation and properties investigation of cermet anode and porous ceramics. Immediately after his graduation, he went to Japan, Nagoya Institute of Technology and worked there as a postdoctoral researcher for more than 3 years under the supervision and collaboration with Prof. Minoru Takahashi and Prof. Masayoshi Fuji. His research in Japan mainly focuses on the synthesis of hollow particles by bubbling template method which was proposed by his group. In 2007, he was awarded Alexander von Humboldt fellowship and went to Germany, Max Planck Institute of Colloids and Interfaces, Golm where he worked with Prof. Helmuth Möhwald and Dr. Dmitry Shchukin in the project of sonosynthesis of protein containers for controlled drug release. In 2011, he succeeded in the application of One Hundred People Project and joined in the Institute of Process Engineering, Chinese Academy of Science in the group of EMMS. His current research interest is to discover the controlling rules behind the diverse mesoscale structures, with the purpose of controlled synthesis of functional materials especially on the biomaterials and energy-related materials.
