I work on stories rather than individual pictures.

What I want is the world to remember the problems and the people I photograph. What I want is to create a discussion about what is happening around the world and to provoke some debate with these pictures. Nothing more than this. I don't want people to look at them and appreciate the light and the palate of tones. I want them to look inside and see what the pictures represent, and the kind of people I photograph.

More than ever, I feel that the human race is one. There are differences of colour, language, culture and opportunities, but people's feelings and reactions are alike. People flee wars to escape death, they migrate to improve their fortunes, they build new lives in foreign lands, they adapt to extreme hardship….

The language that photography has is a formal language. Any photographer is doing something formal. If it's formal, then it must be an aesthetic way to communicate.

What I want is to create a discussion about what is happening around the world and to provoke some debate with these pictures. Nothing more than this.

As in any person's life, there have been difficult moments: I have a son with Down's syndrome; through my photography, I have witnessed all manner of human degradation. But there have also been very happy moments.

I believe that the average person can help a lot, not by giving material goods but by participating, by being part of the discussion, by being truly concerned about what is going on in the world.
