Welcome!

 

This is really only meant as a collection of links I use frequently, so there is no need to send me suggestions for missing links (believe it or not, this happens!). In addition, you may want to browse around the site if you are after my contact details for professional purposes or need a copy of one of my articles. Feel free to drop me a line if you have any queries! Or click here for my academic skills training and public speaking site.

Opportunity for postdoctoral researchers! If you obtained your Ph.D. from a World Top 100 university and would like to work in my group, please get in touch! This is an ongoing opportunity for 2-year appointments directly funded by Peking University. Note, you need to be within 5 years of having obtained your Ph.D. and you cannot be older than 35 on the start date (university rules, not mine).

Prospective undergraduate and postgraduate students already enrolled at Peking University are strongly encouraged to browse the pages under the Science tab. I am always happy to respond to questions or project enquiries -- feel free to talk to me directly! It might be best to drop me an email to see if I'm in my office, but if you happen to be at the Institute and my door is open, you are welcome to come in for a chat :-)

Prospective external PhD students, please note, if you would like to start a PhD project at Peking University, you need to apply to the university directly, through the Department of Astronomy. You can only choose a supervisor after your application has been accepted. I cannot directly take on new PhD students, without going through the university's admission process, so I won't respond to such requests.
