I usually have several things on the go. Whether it is my own drawings for the next work that I am working on while a sculpture is being fabricated or several works at different points in production.

I use whatever media I think will best express my ideas and therefore I don't have a lot invested in the idea of photography specifically. I am more interested in Art.

Thinking is a social process. I talk to everyone from children to anthropologists and philosophers. I try my ideas out on people and they talk back to you. That's how ideas get formed.

In one hundred years time people will look back and think 'these people were really worried about the environment, they were looking at things to do with global warming, and this is why they were making work about these issues'.

Materials are very important to me, and always have been.

My Father is a photographer, so it was always around. I was trained in painting, so I learnt a lot of skills about composition, light, colour, the formal attributes of images.

We always use plywood rather than MDF for structural stuff for the same reasons [stability].
