One of the most critical decision every graduate student faces during the graduate school is the choice of supervisor. Many a times, the dilemma involves joining a senior faculty or a new faculty.
If a student chooses a senior faculty to be the supervisor, accessibility is often a problem. While in the case of new faculty, relatively less brand value in the field seems to be a concern. Apart from these two obvious differences there might be many other pros and cons of the issue.
