The Director of Graduate Studies acts as interim advisor for all students in their first and second year of study. It is responsibility of graduate students to find a research topic and secure a faculty member who is competent and willing, after the second year, to advise them about general examination, dissertation prospectus, and the dissertation project as a whole. Students are mentored by an EAS faculty member as main advisor but are free to take classes and be co-advised by faculty from different departments. As per Graduate School rules, “students may need to adjust their research topics in order to align them with faculty expertise if they wish to complete the degree. […] In cases where, despite all reasonable efforts, no satisfactory advising structure can be found for a student, that student's enrollment and degree candidacy may be terminated.”
