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

I'm an Application Support 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.

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.)

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).

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, but I DON'T answer your questions, and I do NOT do homework. Your homework is YOUR problem, not mine. Do NOT e-mail me with your homework problems or student projects. When I'm not doing something with MATLAB, you might find me playing bridge.
