About EJR-Quartz

Do you have a story to tell? We can help. For more than 25 years, we’ve been writing and publishing science content, with a special emphasis on space. Our science communication services are powered by our multinational editorial team, who transform science into clear, compelling stories.

Our roots date back to 1995 when Co-founders Erica Rolfe and Cees Walen collaborated on the earliest websites of the European Space Agency’s Science missions. Combining editorial and IT skills, this early partnership paved the way for everything we’ve done since, bringing complex research and messages to life. At the heart of it, content matters.
