I manage a multilingual team responsible for covering the Swiss Abroad, providing them with the information they need to participate in political life in Switzerland.
After studying political science in Neuchâtel and Bern, I started out in multimedia journalism at SwissTXT and RTS. Since 2008, I've been working at SWI swissinfo.ch, where I've held various journalistic and management positions.
As a photo editor I am responsible for the editorial use of photography at SWI swissinfo.ch and our collaborations with photographers. When the opportunity arises, I take a camera and accompany one of our journalists.
I trained as a photographer in Zürich and began working as a photojournalist in 1989. I was a founder of the Swiss photographers' agency Lookat Photos in 1990. A two-time World Press Award winner, I have also been awarded several Swiss national scholarships. My work has been widely exhibited and it is represented in various collections.
