Biographical Information

Dr. Jiajun Gu received his B. E and Ph. D degrees from Shanghai Jiao Tong University (SJTU) in 1996 and 2005, respectively. During 2001-2003, He spent 18 months studying at Kyoto University, Japan (Monbusho Scholarship). He started his research career with the team of Morphogenetic Materials headed by Prof. D. Zhang at Shanghai Jiao Tong University in 2005, and is presently an associate professor at SJTU.

 

In the past five years, Dr. Jiajun Gu has published more than 20 peer-reviewed papers in Angew. Chem., Adv. Funct. Mater., J. Mater. Chem., Langmuir, Appl. Phys. Lett., and Phys. Rev. B, et al. Recently, his work “Versatile fabrication of intact three-dimensional metallic butterfly wing scales with hierarchical sub-micrometer structures” (Angew. Chem. Int. Ed. 2011, 50, 8307−8311) was highlighted by Nature as “Materials: Butterfly wings turned to metal” (Nature, 2011, 476, 9). His research interests mainly focused on the bio-inspired functional materials and solutions, either in designing and preparing novel structures, or in exploring the chemical and physical mechanisms of the synthesized products.
