Breaking academic ties with Russia and Belarus

All research and teaching collaborations with Russia and Belarus will be frozen with immediate effect. This means that existing collaborations will cease until further notice and that no new collaborations may be initiated. This means, among other things, that no more financial transactions will be carried out and no more data and knowledge can be exchanged. Also, no more joint events will take place. 

We realize that this is a drastic measure, which is particularly undesirable in a safe world where knowledge can be shared openly. It goes against the principles of open science. However, the situation we currently find ourselves in is exceptional and calls for exceptional steps. We are helping all our researchers to take them as best we can.

We are making an inventory of all collaborations at our university. That inventory is well underway, but of course there may be cases that are not yet on our radar. If you have or know of a partnership that you suspect has not yet been reported, we urge you to report it as soon as possible. You can do this directly with Floor van der Heijden.

The call to freeze cooperation includes formal relationships. Informal contacts and peer-to-peer relationships are not included. In these cases, it is possible for university staff to continue personal and sometimes even desirable contacts with these researchers and lecturers, where appropriate. However, the institution must assess on a case-by-case basis whether contact and cooperation with Russian and Belarusian researchers and lecturers can be continued. For assistance with this assessment or other questions about research cooperation, please contact  

The longstanding and fruitful cooperation with Ukrainian scientists and organizations will continue unabated - as well as it can under the present circumstances.
