Yizheng Wu is a full professor in physics department at Fudan university. He received his phD from Fudan university in 2001, and did his postdoc in Physics department at University of California, Berkeley between 2001 and 2005, then returned back to physics department at Fudan university in 2005. His research interest is to understand the magnetic properties and the spin-dependent transport properties in magnetic ultrathin films, and recent interests include: optically detecting AFM domains in thin films systems; ultrafast THz emission in magnetic heterostructures; spin dependent transport properties in high-quality single crystalline ultrathin magnetic films, etc. He has published more than 160 refereed papers, and received the national outstanding young researcher award of China in 2009.
