I was waiting in line to pay for my food a few days ago when I overheard a conversation between two people whom appeared to be a professor and a researcher. They seemed to be catching up. Among other things, the researcher asked about a company in which the professor had some financial stake. Receiving a positive response, the researcher then asked if the professor ever receives any research money from said company. The researcher received a strong rebuke. The professor answered that he could not in good conscience advise a graduate student’s research while he had a financial interest in his or her work.
