Can I visit for 3-6 months?

Maybe.

For more junior students who want to work on an existing project, short-term visits can be win-win and feel free to get in touch if you may be interested.

For more senior students or postdocs, who want to be driving their own projects, then it’s better if this is in the context of a longer term commitment, whereby you spend a few months here, but we work together for a longer-period. If this is interesting to you, then do get in touch.
