I have a PhD interview in a few days. I am already registered as a PhD student at a university, however I am planning to switch to a different PhD program. My reason to switch are related to the issues with the previous work of my present supervisor that are facing retractions and comments (on pubpeer) for scientific misconduct.
I think that it is better for me find a better lab to prevent any damage to my profile. Should I let the interviewers know that I am already a registered PhD student who is planning to switch due to these reasons? I am not involved in any of these questionable studies and have not published any research with my supervisor. Can this affect my selection chances during the interview?
