I'm a Reader in Cosmology specialising in extragalactic surveys of star-forming galaxies. I've written or co-written about 200 papers so far with over 7000 citations in all, and two books, and co-won a 2004 Daiwa Adrian Prize for Anglo-Japanese scientific collaboration. I'm also a Fellow of the Institute of Physics, a Fellow of the Higher Education Academy, a Fellow of the Royal Astronomical Society and a Chartered Physicist, meaning that I have three F-words and one C-word after my name, all well deserved.
I wrote a paper with George Djorgovski, who wrote a paper with Jogesh Babu, who wrote a paper with Paul Erdös, giving me an Erdös number of no more than three, or exactly three assuming this list is currently complete. This is five less than Erwin Schrödinger. There's a lesson in there somewhere but for some reason I don't feel it's in my best interests to point it out.
