Dr. Salley chairs the Nicholas Foundation's review panel that recommends funds for postdoctoral fellowships. He has just started a collaborative research project with Dr. Strauss. Robert Murphy, a postdoctoral fellow in Strauss's lab, applies for a prestigious Nicholas Foundation fellowship. Because the Salley-Strauss collaboration is new, few outside of their labs know about it. Because Murphy is not involved in the collaboration, Dr. Salley does not consider himself in conflict as a reviewer. He provides a glowing review, and Murphy is awarded a fellowship. But later, when the collaboration becomes well known, other members of the review panel suspect Salley of bias in favoring the Murphy application. As director of the Nicholas Foundation, what would you do?
