I am a PhD student in the Biblical field. I know first-hand (trying not to gossip here) that this professor has lots of problems with his graduate students. Kind of an abusive relationship. It happens that there are certain professors extremely problematic, everybody knows about it and nobody addresses the issue. Unless you do your research properly and thoroughly you might end up experiencing a nightmare and, in the end, quitting the program. I have also hear that that's the case at Vanderbilt with a New Testament professor. I always encourage students to report these issues so the word gets out and people are informed.
