Former collaborator presenting joint research as his own Two years ago, I collaborated* (briefly) with a professor (whom I will call Professor Jim) on some research in mathematics. At the time, I was a PhD student and Prof. Jim was on my dissertation committee. I now work full time outside of academia and Professor Jim is looking for a new position. (Prof. Jim was denied tenure last year). 

Because Prof. Jim is looking for a new position, he is interviewing for numerous positions around the United States. As part of these interviews, Prof. Jim gives a seminar talk on research. The only issue is that, instead of presenting research he performed himself, he is presenting research from my dissertation as if it was his own. No attribution is given to me on his slides (which are a direct copy of the slides I presented at my dissertation defense).** I feel that this is a clear instance of plagiarism. 

My question is as follows:  Should I contact the universities where Prof. Jim presented this research?  Professor Jim has ignored my emails on the matter for three months now. 



*I use the term collaborator very loosely here. Prof. Jim provided a data set for the data analysis. This was not a data set he himself had collected. Rather, it was a data set from the National Institute of Health (NIH) that he had been granted access to. Prof. Jim also attended (while nodding off to sleep at times) some of the early meetings where I presented my thoughts. He gave a few points of feedback and wedged his way onto the associated unpublished paper as an author. (Easy to do when you can leverage your authority over graduate students). I would not include him in a million years if I was in my current, unleveraged, position. The only published source of this research is my dissertation. He does not cite my dissertation in his presentation. In at least one seminar, he made no mention of either me or another colleague who actually did substantive work. (This is according to a contact I have at said university). 

**Many universities publicly announce seminars on their website. Professor Jim has a rather unique real name and Google finds him relatively easily. I have traced several instances of Professor Jim presenting at seminars. Departments are usually happy to send you materials from old seminars if you just email and ask.
Short Answer

No, you should contact Prof Jim and request that he properly acknowledge the source of the work that he is presenting as being your dissertation research.

Longer Answer

You state the work is from your dissertation. You state that Prof Jim was a committee member, meaning he was not your primary advisor. Finally, you claim that Prof Jim is presenting your dissertation work as if it was his own. Let's leave aside how you know this.

First to the case of plagiarism. At its core, this will mean that Prof Jim is giving you absolutely no acknowledgement at all for the work AND that he is claiming explicitly that the work is his. This is plagiarism. What does absolutely mean? It means, not only do you not have any written notice on the presentation, you are not given any verbal acknowledgement during the presentation. Are you certain that Prof Jim does not start or end his talk with a verbal statement such as this: "All of the work that I am showing today was done by Vladhagen who was a graduate student at the time"? Alternatively, are you absolutely certain that Prof Jim is saying something such as this: "To explore this problem, I did this type of study". Absent such evidence, you cannot conclusively prove plagiarism. You can only state that Prof Jim is negligent and thereby potentially engaging in plagiarism.

In summary, your feelings aside, this is NOT a clear instance of plagiarism.

Your case is solely that Prof Jim gives no written acknowledgement anywhere in his written slides for your work. This borders on being dishonest to the extent that Prof Jim was not your primary advisor and the work was your dissertation research. But then, Prof Jim is co-author on a publication. So, Prof Jim does have a right during his presentation to demonstrate the work because it was done in collaboration and is already published as such.

Your case is therefore solely that Prof Jim is taking a negligent approach to acknowledge in writing in his slides that the work is your dissertation research. 

At this point, your first approach must be to contact Prof Jim for clarification. You are at an equal footing here as a colleague. You need only state two things.


I know that you are presenting the research work that we did in collaboration for my dissertation during your interviews.
I am aware that my contributions to the work are being mis-represented because a written acknowledgment is not given on the slides to state that I was the principal contributor on the work.


You have already contacted Prof Jim by email and he has not responded. What does that mean? You have a responsibility now to contact him by phone or visit him directly. In addition, you might engage your primary dissertation advisor. He or she can apply a counter pressure to Prof Jim to drive the point home further. He or she should also be in the better position to inform the universities as needed when the contacts continue to go unanswered.

You are also within your bounds to ask for an official copy of the written presentation, since it represents work that you did.

Finally, as someone on the other side (responsible to do faculty interviews), I can say that faculty are not oblivious to cases such as this. When we interview, we have a CV that lists publications. We hear an oral presentation. We pay attention to whether the presentation fully acknowledges the records in the CV. When they do not, we ask questions. Specifically, when I hear an oral presentation that does not have a concluding list of students who contributed to the work, my alarm bells immediately start ringing. This is NOT NORMAL! In other words, rather than rushing to contact faculty for what you believe could be true, trust that WE will contact YOU should the case reach that level of seriousness (i.e. indications of plagiarism).
