Hello, and welcome to my user page. I live in Japan with my wife and 3 children. I've worked as an engineer in Japan for nearly 6 years after I finished my masters in engineering, but changed paths (slightly) in 2009 to work in the field where engineering and business / economics meet (consulting), where I now work in senior management. I'm not likely to be a frequent contributor, but when I do contribute it will be in areas where I actually have something useful to contribute (i.e. science, engineering, economics, maybe a bit of history and possibly the Japanese language.)
"Yodenshi" is derived from the Japanese word for positron, i.e. "陽電子" - there's no particular reason I picked this other than it being a word I happen to like.
