NWS RSO Annual Conference 2025

Poster winners!

At each annual conference, researchers are given the opportunity to present their latest work and ideas to attendees. This year we were thrilled to receive 35 poster submissions from PhD students of outstanding and innovative quality. You can find the full list of titles below.

Each year three winners are chosen from the submissions and we would like to congratulate Charlotte Nevin, Parisa Samadi, Max Rose!
