Research interests
I'm interested in solving interesting problems and understanding (interesting) truths (mostly in computation and algorithms). This includes for example:
- How can things be computed? How can things be computed efficiently?
- Why (and when exactly) are some problems hard to compute?
More specific things will maybe be added to this list at some later point in time
