From May 31 to June 3, Journalist in Residence Workshop 2019 was held at Tambara Institute of Mathematical Sciences of the University of Tokyo. As for the "Journalist in Residence (JIR)" program in Mathematics and the Journalist in Residence Workshop please look at iTHEMS Newsletter vol 10. This year, there were 11 journalists and 10 participants from RIKEN, 3 from universities and 6 from others. 8 iTHEMS members mainly explained their working field and recent important achievements to the nonspecialists. There were 25 talks in a variety of fields. They were very interesting but the schedule was a little tight. The discussion among the participants continued with joy until very late in the evening as usual. The participants are grateful to the staff of Tambara Institute as well as to the iTHEMS assistants for the great help to organize the workshop.
