Run-Wei Li received his PhD in Physics from Institute of Physics, Chinese Academy of Sciences, Beijing, China in 2002. Then he worked in Osaka University in Japan as a JSPS research fellow from 2002 to 2003. After that, he came to Kaiserslautern University, Germany, as an Alexander von Humboldt fellow. From February 2005, he joined in International Center for Young Scientists (ICYS), National Institute for Materials Science (NIMS), Japan. He studies the fabrication and characterization of magnetic nanostructures, including phase separation and magnetoresistive effects in perovskite manganites, atomic force microscopic lithography in perovskite oxides and fabrication of multi-functional magnetic nanodevices, fabrication and characterization of nanostructures on Si surfaces by scanning tunneling microscopy.
