First meeting with my PhD supervisor In my country, the graduate school and department assign you to a supervisor based on your research and specialization. After admission, you are expected to formally meet your supervisor. 

I never met my supervisor before. How should I prepare for this meeting?
My first meeting with both my PhD and MS supervisor were fairly informal. Talk about research, talk about moving to the new area, ect. Generally set up stuff. They also showed me my new office. You don't really need to prepare unless you don't know much about what your new supervisor does. Relax, there will be plenty of time to stress in graduate school: now is not the time.
