The choice is not limited to the professors who are contributing to the List of Open PhD Positions.
Generally, each professor of Freie Universität Berlin could become your PhD supervisor and can join the FUB-CSC PhD Program later.
To find potential supervisors, you have to check the professor's individual research interests. A good starting point is the List of the Departments of Freie Universität. You can send an e-mail with the information on your research area to the resprective professor you want to become your supervisor. If the professor is interested in your academic background, please send the Beijing Office the name and contact of the professor that we can include him/her and your application into the FUB-CSC PhD Program. Then, the professor will submit a PhD offer for you, and you have to submit your application documents to the Beijing Office by January 4.
