I have a bachelors in biochemistry and am currently working as a research technician, doing wet lab work. As of late, I have become more interested in the field of computer science. I would especially like to go into a field that is the mix of biochem and compsci (bioinformatics/computational biology). However, I have never taken a single computer science class, though I have been trying to learn Perl & Python on my own. How can I make the jump from biochem to a more computational related field? Most places, even for entry level jobs, won't hire me due to my background and have I never taken a computer science class.
