I'm about a year into some exciting research, with some early results that many professors are interested in following the progress of. I have two advisors.
I recently learned that my graduate classmate, from a different lab, has been shopping my ideas around, interviewing with other labs at other universities, apparently to try to do something similar, gain a collaborator, etc. He told he did this, which made me uncomfortable.
He's also contacted one of my advisors, he says. I believe there is no stopping him at this point. He will likely contact my second, more renowned advisor too, with the goal of working with them, and knowing about all of my recent progress in research, since him and I are very close friends.
I feel he's behaving like a leech and acting like a desperate leap-frogger. And I regret talking so much about my progress, which he now uses and shops around, perhaps misrepresenting the ideas and techniques as his own.
How should I deal with these feelings?
On the one hand, I feel he has complete freedom to contact whomever he wants, and shop whatever unpublished ideas he wants, to build his own career. On the other hand, I feel like I am just supplying and enabling a plagiarist.
Should I cut contact with him, or be proud that he is excited about my work and wants to emulate me?
I don't contact his advisors or shop his ideas around, for example.
