The ICT4S 2023 Doctoral Symposium is an opportunity for PhD students to discuss and receive feedback from a panel of experts in the community, as well as their peers. The ICT4S 2023 Doctoral Symposium is a great opportunity for any doctoral student who has already settled on a dissertation topic and whose doctoral research will benefit from external feedback from peers and experts in the community. Sustainability is a broad field, so we independently assessed then ranked the submissions, agreeing on a selection of 10 we felt were most clearly relevant to ICT4S. A key factor we considered was also that there was suficient time remaining in the studies to actually benefit and action the feedback received at the doctoral symposium.
