Schedule

The course will last 5 days and will be a mixture of lectures and practicals. In order to get the 2.5 ECTS, the students will have to submit a report, consisting of one of the following:

  • A poster on their own research (to be presented during the Monday poster session), OR
  • A selection of exercises made during the practical sessions (details will be given during the course).

Details on social programme

  • On Thursday, directly after the lectures (1615), we will be picked up by a bus that takes us to the center, where we will go on a canal tour of Copenhagen. Please bring an umbrella in case of rain :-)
  • After the canal tour, we will walk to Kulturhuset Islands Brygge, where we will have a conference dinner from 18:30. This culture house is beautifully situated near the water.
