You can contact the potential supervisor of your PhD-thesis directly, sending your CV and research plan. Please be sure that you tie in with former publication or current research projects from the potential supervisor: generic application and applications without a point of contact won't be accepted.
The best opportunity to get in contact to a supervisor is certainly a personal conversation, for example at a conference, if you cannot meet her or him here in Erlangen / Nuremberg directly.
He or she must agree in supervising your planned research work before you can start doing your doctorate at our University.
