My degree is in Biology, but I learned how to program shortly after changing to Linux by poking into the source of the programs I use.
I mostly program in perl for bioinformatics (where I contribute to the BioPerl project) and Octave for image processing, but am capable of reading and hacking in C++, bash, python, and R.
For full disclosure, I am an Octave developer and maintainer of Octave's image package.
