I have a fairly unique situation going on that I'm not quite sure how to handle. A colleague of mine completed her PhD two years ago on the topic of arts and the local community. Since she was computer illiterate, she hand-wrote her entire thesis. Her advisor delayed in reviewing her work, asking for money from the student before beginning to review but she refused to pay (according to her). After a while, the advisor told my colleague that he would take care of having the thesis typed up himself, and did so. She paid the typing and printing cost. (Also, for context, it's fairly common not to know how to operate a computer in my region.)
At that point, this advisor asked for my PhD thesis, which I had recently completed. I handed him a soft copy.
Recently, my colleague and I were reviewing our theses, we noticed blatant plagiarism between the two versions. My colleague then remembered that her advisor has mentioned that he "edited" her thesis to "make it more informative". She immediately informed the university about the plagiarism and has put in a request to rescind the degree, as the no longer feels she deserves it. Unfortunately, the press found out about this story, and it's now in the public eye.
My question is, what can I do to protect my reputation at this point? I've since done some research and believe I have found other examples of this advisor both demanding money from students before graduating them and plagiarizing work on PhD papers. I've presented this to the Vice Chancellor, and he seems to believe the evidence, as we're not the first ones to complain about this type of behavior from this advisor. Still, with all that said, is there anything I can do to clear my name and expose the advisor?
