Professor Stahl and his students aren't the only people who work on designing catalysts. In fact, many researchers work on similar projects. For this reason, many researchers collaborate with other researchers. These researchers could be at the same university, at a different university, or they could work for a government agency or a business.
Additionally, some research projects involve work in many different research areas. In this instance it is necessary that researchers work together to solve a problem. In order to further their understanding of the research area, and to get a new perspective on their project, researchers often work with other people!
