I'm a grad student studying a field known as bioinformatics. Basically, we come in to do the computer work for the biologists. We are in very high demand, as most biological research today generates huge quantities of data, and most biologists don't have the skills to deal with it.

The good news for someone like you is that I've met a number of people with a lot of experience in the computer side of things but little to no biology knowledge. There are in fact a lot of projects that could benefit from a good programmer/data analyst even if they don't know much biology. A lot of bioinformaticians just pick up the biology they need to know about their project as they go. Grad school would also be another route. A lot of bioinformatics programs are catered to people lacking either the biology or computer side of things. A good student could get into one of these programs without needing to go back and do a separate undergraduate degree.

I hope that helps! It's too bad that you can't pm people through this site, or I'd have no problems answering any questions if you were interested in hearing more. That said, there are a number of friendly online communities, such as the bioinformatics subreddit.
