I'm a customer success engineer at MathWorks Japan. My addiction to MATLAB got me into MathWorks. I love showing MATLAB, talking about MATLAB, and thinking about how to make MATLAB an even better tool. For 8 years, I was an application engineer at the headquarter, and then I was a training engineer for 4 years at the Japan office, and now I'm a customer success engineer.

I am also one of the bloggers for File Exchange Pick of the Week - http://blogs.mathworks.com/pick.
Professional Interests: data analysis, gui building, data exploration, data visualization, biomechanics

Note: Please do not send me individual messages or questions, as I will not be able to respond to them. If you have technical questions about MATLAB, please use the various resources on MATLAB Central. If you have a valid license, you can also use Technical Support.

DISCLAIMER: Any advice or opinions posted here are my own, and in no way reflect that of MathWorks.
