The bounds of traditional academic subjects have been moved, crisscrossed, and overturned as researchers think about their research problems in new ways. Giselle Knudsen trained as an enzymologist, but now she is learning how research has changed. "Enzymologists are becoming proteomics experts and they are interested in classical pharmacology, but they don't call it that anymore. They are making up all these new words," says Knudsen, a postdoc at Purdue University.
