I like to be outside. But if I'm inside, I like to be using MATLAB.

I'm an Application Engineer at MathWorks and civil/structural engineer by education.

Some Interests:
-Image Processing, specifically 3d images (CT, mri)
-All things graphics
-Optimization: both of code and objective functions
-Finite Element Analysis

The two things I want to improve on most are regular expressions and OOP.

Mainly retired from Eastman Kodak. (Of course, Kodak itself is now semi-retired. I don't think I had any influence in that.) I still write MATLAB code as I find something interesting, and I do attempt to write new tools to put on the File Exchange when I think I can make a contribution.

However, I DON'T answer your questions, and I do NOT do homework. Your homework is YOUR problem, not mine. Please do NOT e-mail me with your homework problems or student projects. If I was willing to answer your questions, I would very rapidly become overwhelmed, because one question is never just one simple question.

When I'm not doing something with MATLAB, you might find me playing bridge, either in the club or online on BBO.

Professional Interests: MATLAB, numerical analysis, mathematical modeling

Avocational interests: Bridge, woodworking, woodturning

I write documentation for MATLAB mathematical toolboxes, primarily optimization and PDE. I have also written documentation for statistics, symbolic math, and econometrics.

My pre-MathWorks job was with Bell Labs, primarily in mathematical models of data traffic, with a strong interest in parallel computation and in rare events (large deviations).

I love MATLAB. I love teaching people to love MATLAB.

I love it so much that I went to work for the people who make MATLAB. I spend my days at MathWorks creating material to help people learn MATLAB. Life is good.

(My love of teaching MATLAB notwithstanding, please don't email me for help -- post a question to MATLAB Answers instead. Firstly, your email will probably be swallowed by my spam filter. Secondly, private consulting isn't in my job description.)
