Hey everybody, My friend is in graduate school and has been having problems with his adviser. Let me back up a bit here, they used to be on good terms, but more recently his progress has stagnated because his adviser won't meet with him. Also, his adviser has been losing patience due to his lack of progress. He is getting really fed up and this has impacted his relationships, including his one with me. How would one go about mediating disputes between an adviser and a student tactfully?
