Wenshan Cai

Wenshan Cai joined the faculty of Georgia Institute of Technology as an associate professor in January 2012. Prior to this, he worked as a postdoctoral fellow at Stanford University for three years after receiving his Ph.D. from Purdue University in 2008. His impact on the evolving field of plasmonics and metamaterials is exemplified by over 3,000 citations of his recent papers. He authored the book Optical Metamaterials: Fundamentals and Applications (Springer, 2010), which is used as a textbook or reference at many universities around the world. He leads the Laboratory for Advanced Photonics and Optoelectronics (LAPO) at Georgia Tech, which is focused on the design and implementation of nanophotonic materials and devices.
