Hello All!

I have found out that a colleague whom I share a supervisor with has appropriated someone else's work, delivered it at a conference as his own, and not given any reference to the actual researchers. In addition to this, I have been pre-warned by two colleagues that he will either try and manipulate and piggyback on your work / or will try and make moves on you (which has happened) - The latter part I can deal with, but I am concerned for my supervisor who is really out there working at an international level with some amazing research connections, should I talk to him about how this person has treated other academics or should I just sit back? I know that plagiarism is a no no, but I do not know how it impacts on the big picture - i.e., will it even be a concern for my supervisor??

Thanks for your help, 'ppreciate your time.
Lewis,
