Sure, go in to bioinformatics research. You might even end up doing something that benefits humanity more than trying to make the next Facebook! Data is piling up faster than we know what to do with it.

There are a lot of problems to be solved that might benefit from computer science. De novo Protein structure and function prediction, better alignment from noisy data, drug target discovery, homology modeling in the twilight zone, better ways to share the data that we do have, better databases to store the data from high-throughput experiments, better ways to compare pathways and biochemical networks, and all of the other things that I could go on to list.

There is no shortage of problems to be solved, only shortages of good people and funding.
