Gianna-Carina Grün

(Online|Data|Science) journalist

Hi, I'm Gianna! I built and currently run DW Data, the data journalism unit at DW. As a dedicated online journalist I'm passionate about the multimedia storytelling opportunities the web offers. If you don't find me raving about this, I'm producing cool data visualizations and insightful data-driven stories and spread enthusiasm for data journalism as a ddj trainer.

I enjoy building things: Both, online – using code to create data visualizations and applications – as well as offline – using my project management skills to craft workflows and teams (or my actual hands for woodworking). Trained as a biologist, I combine analytical thinking with my journalistic curiousity to actually do what I thrive at: Constantly learning new things.

About me

Since June 2017, I'm the Head of the Data Journalism team at Deutsche Welle (DW), Germany's international broadcaster. Previously I worked for the interactive background magazine Der Kontext, where I explored non-linear storytelling. Before that, I was a multimedia editor for environmental topics at DW Global Ideas. The position I learnt most in was being the Head of Online at Life Links, transmedia magazine I co-built from scratch.
