MS and PhD Student Leaders

Representatives to GSA, GPSS and SAYPH

The Graduate Student Assembly (GSA) is an elected body of graduate students that represent all Ph.D. students and master's students in the Graduate School of Arts and Sciences (GSAS). The GSA works closely with Yale administrators, including the Dean of the Graduate School, to advocate for and improve graduate students' academic, social, and living experiences at Yale.

The Graduate and Professional Student Senate (GPSS) fosters interaction among students through community service and engagement, social gatherings, and academic and professional events, as well as to support official and unofficial student groups. GPSS also represents the graduate and professional student population on official university committees.

The Student Association of Yale Public Health (SAYPH) is the student government for the Yale School of Public Health. MS and PhD students are also represented through this body.

Please reach out to these MS and PhD representatives to both bodies to share your concerns, suggest initiatives or learn more about the Yale School of Public Health and Yale University.
