If you are interested in pursuing a PhD or postdoc, please contact me.
The topics you’d be working on are 100% up to you, if you’re a postdoc. I believe in total freedom in research, because I always had it myself, and won’t interfere at all with them.
If you want to join as a student, I would have to bug you from time to time to see how you progress. I will of course be able to suggest a couple of ideas if you want, but I would prefer that you have your own, and I will keep reminding you of that.
