8-12 August 2016, Johan participated in a seminar “Coding Theory in the time of Big Data” at the beautiful Schloss Dagstuhl. As is common at Dagstuhl, the seminar had only few talks, leaving ample time for discussion and collaboration on the seminar’s topic. Johan worked mostly on finding new good rank-metric codes and on private information retrieval schemes. He also gave a short talk on Coding Theory in SageMath and the upcoming SageDays 75 on Coding Theory.
