Call for Contributions

The workshop builds on a highly successful first workshop last year, but focuses the discussion on specific topics and encourages participants to arrive at specific research challenges that can be tackled in concrete research designs. The output will be published as a report.

The workshop is an interactive event focusing on discussions and inspirational exchange between participants on challenging new research questions. We do not wish to prescribe topics for challenges, but encourage proposals to think outside of the box and propose challenges that lie ahead rather than research problems that are currently being tackled.
Please submit your description of a research challenge in which you

  • argue for the concrete motivation behind this challenge,
  • set it in relation to existing work,
  • provide a context that enables understanding and further investigation and
  • outline, if possible, concrete research designs to tackle the challenge.

This includes questions such as the following

  • Why is this topic relevant?
  • Why has it not been addressed yet?
  • What are the problems involved?
  • What is the potential impact if this is successfully addressed?
  • What are possible ways of evaluating if it has been addressed?
