Associate Professor of Materials Science & Engineering PhD '96: Metallurgy, Kyushu University (the last metallurgy degree in Japan)  MS '93, BS '91: Metallurgy Kyushu University Masashi Watanabe'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 ζ (zeta)-factor method for quantitative X-ray analysis and implemented multivariate statistical analysis (MSA) for spectrum images of X-rays and energy-loss electrons. Masashi spent his first scientific career as a postdoctoral research associate at Lehigh until 1998 after he obtained Ph.D. from Kyushu University. He was an associate professor at Research Laboratory for High Voltage Electron Microscopy in Kyushu between 1998-2001. Then, Masashi returned to Lehigh University as a Research Scientist. In March 2007, he joined to National Center for Electron Microscopy in Lawrence Berkeley National Laboratory as a Staff Scientist mainly assigned for analytical electron microscopy. At NCEM, Masashi also participated in the TEAM project. Masashi's third journey to Lehigh was made in January 2009. Masashi received the K.F.J. Heinrich young scientist award from the Microbeam Analysis Society in 2005 and the Kazato Prize from the Kazato Research Foundation in 2008. Masashi's MSA plug-in package for Gatan DigitalMicrograph is now commercialized from HREM Research Inc. in 2009.
