My name is Sihai Liu. I come from Beijing, China. I got a master’s degree from the Capital Medical University. I’m an orthopedic surgeon at the China Rehabilitation Research Center（CRRC）. I am very glad to be here as a visiting scholar. I will work with Ping Wang for one year. I hope I can adapt to the work here soon. My direction is trama and joint surgery. In my spare time I like sports like Badminton and running.
