I regularly serve in the Scientific Organising Committees (SOCs) and Local Organising Committees (LOCs) of International Conferences and Schools, whose list would be too long to report here.

I am also passionate about reaching out with my research. Over the years I have produced many images from the simulations that I have carried out. Many of them have been used by me and others for public outreach and have appeared on newspapers, magazines, calendars, and, of course, online. These can be found of them after searching for “black holes” or “neutron stars”. Some of these images have also won prestigious awards. Animations of my simulations have ended up on the NASA YouTube totalling more than 6,000,000 downloads, eventually ending-up on the New York Times. In addition, I regularly provide interviews on popular radio shows in Germany (Deutsche Funke) and abroad (BBC, RAI), some of which have also appeared on journals such as The New Scientist.
