I am interested in a PhD project which will be supervised by somebody who has never supervised a PhD student before. In fact, this research group is not yet completely established. On their website they mention that this research group is starting to work in this new department very soon (the exact date is known, but I am not sharing for the sake of confidentiality).
When the department starts to be open soon, this project (advertised PhD position) will be the first project they will be working on.
Although I like this project, I am not sure how risky it is to do your PhD in a newly open group with inexperienced supervisors. What are the risks? Also, are there any potential benefits apart from risks?
Update 1 (based on the comment by @lighthousekeeper): On their website, they have shared a Resume of the supervisor where I could only see the section "Master thesis topics I supervised". As I did not see anything about PhD, I drew this conclusion that the supervisor may have never supervised a PhD student.
Update 2 (based on the comment by @Buffy): Yes this is a new department (in fact still about to be open, so not yet completely open). The university was established 35 years ago (so relatively new). Yes, I think the department is pretty small.
