„Theoretical computer science reminds me of doing a jigsaw puzzle, or more precisely, an abstract jigsaw puzzle. Even when the „puzzle pieces“ can have any kind of dimension, the problems stay similar. It is possible, that a (incompatible) “puzzle piece” is tried out again, because visually it looks as if it would fit. However, as soon as the puzzle is finished, the overall picture seems to have been obvious from the beginning.
Already during my school education, I had a great interest in computer science. Though computer science does not have to be a school subject in order to study the subject at university, it definitely helped me to develop an interest in the subject."
