Research: Previously, I studied Pulsars with Prof. Renxin Xu at Peking University as an undergraduate student. I'm now working on pulsar wind nebula and something related to the braking index.
Courses: I am writing notes on High-energy astrophysics course now. Feel free to dowload and read. It's better to read online, because I am updating it all the time. Comments are welcome. My English writing is horrible. Comments on non physical problem are also welcome.
