For a PhD candidate entering graduate school, the first several weeks are exciting. Besides starting classes, the student must decide which professor’s group to join and which research project to work on. One word of advice here. Make sure the topic starts out focused on a specific research topic.

A vague, open ended research topic can be a lot of fun at first but can meander without producing much material for a research paper much less a thesis. My own experience is a good example. My professor departed for a sabbatical soon after I joined his group.
