Sharp. Intelligent. Cold-blooded. Ruthless. I void warranties.

It might look like I'm doing nothing, but on a cellular level I'm really quite busy.

The «Cent-Vues» was the first small-format camera ever marketed using the 35 mm film format.

I'm a scientific and technical journalist, a freelance writer, a webmaster and a graphic designer and desktop publisher. In other words: I'm a web scientist and a pixel print craftsman. I also used to be a biologist and a zoo keeper, and to this day I've kept a strong interest in natural sciences. In my free time, I direct some plays (or play on stage) for an amateur theatre association. I live in Fribourg (the Swiss one), a very nice bilingual city (French/German), but grew up in the Italian-speaking region of Switzerland. If you wish to contact me, I can understand French, Italian, English and German: your choice!

Using my pictures

My photos are usually under a Creative Commons license, which means you are free to use them (non-commercially), but that I ask for attribution in return (my name, and a link if possible).

Some photos (mainly of our rehearsals and/or stage plays at the Théâtre de la Cité de Fribourg) are sadly not available under a Creative Commons license, for various reasons I have no decisive influence upon. Thank you for respecting this.
