Dr. 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 zeta-factor method for quantitative X-ray analysis and implemented multivariate statistical analysis (MSA) for spectrum images of X-rays and energy-loss electrons. Dr. Watanabe has obtained research funding through federal grants from the National Science Foundation and Department of Energy, as well as from industry, including Bechtel Bettis Atomic Power Laboratory, Knolls Atomic Power Laboratory, and Northrop Grumman/Nano TEM Inc. He has more than 80 research publications and has given more than 70 invited talks and presented at numerous additional conferences.

Dr. Watanabe is affiliated with Lehigh University's Center for Advanced Materials and Nanotechnology, where he served as a research scientist prior to joining the faculty. He also has been a scientist at Max-Planck-Institute fur Metallforschung in Germany, University of Sydney, and the National Center for Electron Microscopy at Lawrence Berkeley National Laboratory. Dr. Watanabe has received awards from the Microbeam Analysis Society, International Symposium for Testing and Failure, The Kazato Research Foundation, The Japanese Society of Electron Microscopy, and The Japan Institute of Metals. He is a member and director of the Microbeam Analysis Society and a member of the Materials Research Society, Microscopy Society of America, Japanese Society of Electron Microscopy, and Japan Institute of Metals.
