Students who have fellowships or are privately funded need to associate themselves with a faculty member who will supervise their thesis research. They should choose a supervisor in much the same way as another student would try to secure an RA, identifying prospective faculty members and checking whether there are projects they can work on. Research requires money, and even though these students require no salary from the Department, they are well advised to find a supervisor who has some funding for the intended work. Although their obligations to the research are not the same as those of an RA, in practice they end up working just as hard in order to finish their theses in a reasonable time. It is usually a good idea to associate with a supervisor as soon as possible after arrival at MIT. The student then becomes part of a research group, gets a desk to work at, and is in a position to get advice and learn from his/her supervisor and from the more experienced students in the research group.
