Jingyun Huang is a Professor at the School of Materials Science and Engineering, Zhejiang University. He received his B.Sc. from the Department of Physics, Jilin University in 1990, and earned his M.Sc. in 1997 and a Ph.D. in 2000 from the Department of Materials Science and Engineering, Zhejiang University. He joined the Department of Materials Science and Engineering, Zhejiang University as a Lecturer in 2000, was promoted to Associate Professor in 2001, and then to Full Professor in 2009. He was a Visiting Scholar at the National Singapore University (December 2003–March 2004), a Visiting Scholar in Professor Lieber’s group at Harvard University (November 2004–December 2005), and a Visiting Scholar in Professor Zhonglin Wang’s group at Georgia Institute of Technology (December 2005–December 2006). Now his research interests mainly include the preparation of semiconductor thin films for light emit devices and micro/nano porous function materials for biosensing. His recent work mainly includes p-type doping of ZnO thin films by laser molecular beam epitaxy or metal-organic chemical vapor deposition and its fabrication of light emitter diode and laser, the synthesis and optical properties of oxide nanostructure material for biosensor applications.
