A newer PhD student in my lab has begun conducting research very similar to mine. We are both working on a large body of research, and although the projects are similar, their research will ultimately be complementary.
I have been working with certain collaborators for >5 years, even before starting grad school, and the new student has been reaching out to them for samples. The collaborators recently met with me out of concern for the direction of the new students work, and have asked me to ‘oversee’ the student’s research.
Personally, I have had my own concerns with the highly enthusiastic new student, who intends to use irreplaceable high value samples, but still has little lab or research experience in this area. Additionally, I have talked to the student in the past about the importance of our samples, especially with regards to our collaborators, and they continue to act with confidence as though they can do whatever they want.
At this point, I want to bring in my advisor, since it’s not my responsibility to oversee a fellow PhD student. I don’t want to come off as being petty or just complaining about the new student, but also need to maintain good relationships with our collaborators who put a great of trust in me with their samples.
Any advice on how to move forward? Suggestions for reigning in the enthusiastic new student while also saving face?
