       Hi guys, I'm Joe, and I'm back as the PGR Rep! This time, however, I'm actually a Ph.D. student, so I feel more equipped to represent our smallest, but still very important group! On committee, my main role is to represent our wonderful students studying hard for a Ph.D., as well as accommodating them and encouraging them to attend CSS' events. However, I'm always happy to chat to everyone, not just PGRs! Outside of uni work, you can find me Ballroom & Latin dancing, or enthusing over many, many insects.

       Hi! I’m Maddy, a PGT student studying AI and Machine Learning, and I’m excited to be your new PGT Rep this year. As someone new to UOB, I’ve jumped straight into getting involved and connecting with our community. Outside of studying ,I’m a massive gamer and a pretty terrible netball player . My goal is to represent and support all PGT students, making sure everyone feels welcome, included, and heard.
