The milestone reflects decades of investment in research, critical thinking and knowledge production on some of the world's most pressing development challenges. ISS PhD graduates have gone on to become researchers, educators, government officials, policymakers and practitioners across the globe, contributing to change in diverse contexts.

More than a celebration of a number, the milestone speaks to the strength of the ISS research community and its global network of scholars. Together, these 300 graduates represent a growing body of knowledge and a shared commitment to understanding and addressing complex development challenges.

The commemorative booklet serves as both a record of this achievement and a tribute to the people who have helped shape the ISS PhD programme over the years.
