The GSE Partnerships program is a peer mentorship model designed to empower students to help each other navigate the “hidden curriculum” of the GSE. Through these interactions with advanced doctoral students, we learn how our classmates and colleagues have “managed ambiguity” at different stages in their graduate careers. How does a first-year PhD student learn to navigate relationships with professors and advisors? How does a master’s student decide whether doctoral studies are right for them? Who can a graduate student turn to for advice about classes, research, or work-life balance?
