We would like to inform that due to the Covid-19 epidemy, this year's edition of our Doctoral Research Conference was cancelled. Those who have registered will be notified in case we obtain the permission to accept either recording or a written handout of a presentation as a conference contribution (for Research Poster presenters, the pdf-file must be attached). We are sorry that we will not be able to meet at DRC 2020, but if all is well, we hope to see you next year!
