Hi, I'm
Gianna-Carina Grün
As a data-journalist, I turn datasets into stories that matter. I'm mainly working for DW Data, the data-driven journalism team that I founded in 2017 and develop further since. Beyond that, I also work as a data journalism trainer for both experienced journalists as well as journalist trainees. In my spare time, I'm pursuing a PhD investigating how well elaborate chart types are understood – and how we might improve that as practitioners.
Publications
When I'm not editing or working on strategic tasks, sometimes I get the chance to also write and publish stories. Here's a preview:
