Please do not send any application materials to me. 
University policy requires that you apply for admission by the normal procedure, which is probably best, since I likely could not give your application the time and attention it deserves. For fairness to everyone, I will not respond to anyone's e-mail that asks me about admissions. Here is the standard contact page supplied by our Board of Graduate Studies. Read this first, and if you have additional questions please contact admissions@gradstudies.cam.ac.uk. If you are interested in research, try to be persistent - this is a hugely rewarding career!
