I really enjoy teaching in the undergraduate problems classes and giving something back to the students. As a PhD student, the camaraderie between us is very good as we are all working towards the same goal - for example, we have a weekly seminar group run by the students of number theory which is aimed specifically at our learning needs but because we are all interested in the topics and it is a relaxed atmosphere, it is really conducive to working.
I've always found the staff to be helpful - often, if I go to see someone out of their set office hours and they are free, they will take time to talk to me and if they aren't sure on something, they will point me towards someone else who might know better.
I am President of the hillwalking club which runs a walk in the Peak District every Sunday and has a different social every Wednesday. It's a great way to meet new people and escape from Nottingham for the day to relax and forget about work. I also organise 5-a-side football matches each week for maths postgraduates and lecturers. I'm also a member of the glider club as well as the snooker and pool club.
There is a great social atmosphere at the university - so much so that it can be hard to find time to work sometimes! One of the things I like most about The University of Nottingham is that there is always something going on and something for everyone - from free monthly quizzes organised by the Postgraduate Student Association (PGSA) to nearly 300 different clubs and societies.
I would advise becoming as involved in the university as possible - whether that be joining the Maths Society and going on socials, or running for a committee position on another club or society, or writing an article for the student newspaper.
