In this first meeting, the courses you have attended, your special interests, and if you would prefer a theoretical or a practical topic will be discussed. The goal is to find a topic for you, which fits your expertise and interests perfectly.
Usually in a second meeting, a topic will be suggested to you. You will then have sufficient time to think, whether this fits your expectations. Of course, if you don’t like it, alternative topics can be found. You are also welcome to suggest your own topic.
