Just Don't Touch Anything

On his blog, Russ Altman discusses the "proper role" of bioinformatics -- and bioinformatics researchers -- in biomedical research. He says that bioinformatics researchers need not perform wet lab experiments, especially early on in their careers. They do however, he says, need to understand what's going on in the wet lab. "It is also very critical that bioinformaticians understand the experiments that they analyze in great detail -- otherwise risking irrelevant methods that don’t make valid assumptions about the data," writes Altman.
