 Welcome, or rather welcome back if you're a graduating student. It's wonderful to see you all here at this, our first graduation ceremony of 2013. My name's Paul Webley. I'm the director of SIAS. I've been an academic for 34 years and I've attended dozens of degree ceremonies, but they still bring a lump to my throat and often tears to my eyes. It's really a great experience to look out and see the lobenhall shimmering with pride, especially on this side of the room. I've been a parent of a graduating student twice, last time I was in 2007. I can remember every detail of each graduation and they really are one of life's defining moments. To be honest, I don't think I understood graduation until I was a parent. So thank you, students, for coming and giving your parents such a great day and I empathise with them. Now I'm delighted that we can share this special day with the family members and friends of graduating students all around the world who are unable to make it today. So the ceremony is being streamed live on the internet. So try not to pull any funny faces if the camera might be on you and my colleagues behind me please don't go to sleep because the camera will certainly be on you. I'm sorry to say that our president, Grashah Michelle, can't be with us today for obvious reasons and our thoughts are with her and with Nelson Mandela. So today's ceremony will be presided over by Tim Miller, the chair of our governing body. Tim's been a wonderful chairman of science for the last five years. He's been incredibly engaged, supportive and critical. He's there when needed and he's there when needed today. So Tim, thank you very much and Tim, over to you.
