MCR Executive Committee

The MCR is run by an Executive Committee (often simply called the ‘Exec’) composed from its own members. They are here to serve the MCR community, organising events for its members, represent them to the College and University, and oversee the day-to-day running of the MCR. If you ever have any need for them or wish to make comments or suggestions, they are always happy to receive them. 

Callum Bowler

I’m Callum Bowler, a first-year English PhD student. As Castle MCR President, I oversee the running of the MCR, as well as representing the wishes and views of the MCR to both the College and the University. I also take responsibility for relaying the thoughts of University leadership to the MCR when relevant, and liasing with Castle JCR and SCR as well as the MCRs of other Durham colleges. I aim to ensure that all Castle MCR members are as socially and as academically fulfilled as they can be during their time at Durham. 
Please don’t hesitate to get in touch at if you have any questions, concerns, or anything at all you’d like to discuss relating to the MCR or Castle life.
