In my lab there is currently an open Phd position (closing May 25th):
There are also funded opportunities to collaborate between universities. To facilitate this our university can offer an extension of an ongoing project (at another university) for a period of 9 months up to 1 year (3 or 4x3 months).
Similar opportunities are also available for postdocs and professors for periods for 1-3 months.
Let me know if you are interested or like more information.
