Ph.D. Exchange Scholarships (PhD.X)

2 Calls a year: June 15 and November 15

The RUB Research School awards Ph.D. Exchange Scholarships (PhD.X) to international doctoral researchers within an international research cooperation of RUB and international partner institutions. We understand this programme as a structural support fostering RUB's international research network and a support for early career researchers from abroad.

The invitation of international doctoral researchers for a three- to six-month research visit is to take place within the framework of an already existing cooperation. Besides the scientific collaboration and its benefits, guests are encouraged to get to know the German academic system and culture as well. Reciprocally, we hope that RUB researchers receive an invitation from the partner institution in return. Please note that the international guests are expected to hand in the application package.

We are convinced that this vivid exchange programme will sustainably support RUB’s international research collaboration.



The programme aims to support and strengthen the international research network of RUB. International doctoral researchers can apply for a scholarship if they are involved in existing research cooperations. They have the opportunity to work on their doctoral research projects in Germany. With PhD.X we intend to initiate, revive or expand a bilateral exchange of doctoral researchers and, accordingly, RUB Research School hopes that the partner institutions invite RUB students for research stays in return.

The supported doctoral researchers will become members of RUB Research School for the time of their research stay. They are welcome to participate in RUB-RS activities and benefit from the doctoral community on campus. Thus, we hope to enrich the interdisciplinary dialogue and networking amongst our young researchers.


Please consider content and handling of the cooperation letter for the Ph.D. Exchange Programme.

More than one doctoral researcher can apply to the same chair or working group at RUB for the same or overlapping time period.

The inviting chairs are expected to take over organisational responsibilities related to the research stay at RUB.



The scholarship holders directly receive a monthly amount of 1,000 € for the time of their research stay (3 to 6 months).



International doctoral researchers are eligible to apply if they have obtained a Bachelor or Master degree from a university outside Germany and are officially accepted/enrolled as doctoral researchers at their home universities.

The department, institute or chair at which the visiting doctoral researchers are pursuing their respective Ph.D. projects must have an existing research cooperation with a chair or working group at RUB. Applicants have to be involved in this cooperation. The research collaboration has to be documented by a cooperation letter acknowledged by responsible scientists at RUB and the international cooperation partner (see section “apply”).
