Now, I am coming from Japan (Oita National College of Technology) as a visiting scholar. I graduated from Toyohashi University of Technology in Japan with a Bachelor's and Master's degree in Production Systems Engineering (However, I belonged to the laboratory of Material Science) in 1987 and 1989, respectively. After that, I received PhD in materials science and engineering from the Nagoya University (Japan) in 1999. The title of my PhD thesis was "Study on deformation and fracture behavior and electronic state of solute atoms in chromium." During my stay at Northwestern University as a visiting scholar, I am mainly investigating about the corrosion characteristics of the aluminum foams, and change of the mechanical properties by corrosion. I believe that it is applicable as processing of the new type foams which we do not know right now.
