If you have another school year before graduation, you should also seriously consider doing some work in a campus biology lab. If you're at a larger school, there will be at least one lab that does computational biology work, and if not...well, it's important to know something about biology. A winter spent in a lab will be a learning experience, either way.

And if you're having trouble getting your foot in the door, here's an easy way to get a gig in a campus lab: work for free. Tell them that you're a CS student interested in computational biology, and that you'll be free, eager labor if they'll let you learn about biology research. It's a time-honored tradition -- nearly everyone in the field gets their start this way.
