Masashi Watanabe is a Staff Scientist at National Center for Electron Microscopy in Lawrence Berkeley National Laboratory. Masashi's research emphasizes materials characterization using various electron microscopy approaches involving analysis via X-rays and energy-loss electrons in analytical electron microscopes (AEMs) and atomic-resolution high angle annular dark-filed (HAADF) imaging in scanning transmission electron microscopes (STEMs). He developed the z (zeta)-factor method for quantitative X-ray analysis and implemented multivariate statistical analysis for spectrum images of X-rays and energy-loss electrons. Masashi obtained his Ph.D. in Metallurgy from Kyushu University in 1996 and was a postdoctoral research associate at Lehigh until 1998. He was an associate professor at Research Laboatory for High Voltage Electron Microscopy in Kyushu. Then, Masashi returned to Lehigh University as a Research Scientist in 2001 and promoted to a Senior Research Scientist in 2004. In March 2007, Masashi joined to NCEM as a Staff Scientist (and became a TEAM player). In Masashi's many years at Lehigh, he was closely working with Prof. David Williams. Masashi received the K.F.J. Heinrich young scientist award from the Microbeam Analysis Society in 2005 and has been a lecturer in the AEM course at the Lehigh Microscopy School since 2001. He has published over 100 articles.
