Once in an area of conflict, how do you decide where to go and what to shoot?
"I first evaluate what the key elements for the story I want to tell are. I am usually interested in the civilian aspect of a conflict, so will look for the best ways to cover that element of the story. That informs my decision making process on where to go and what to do. Usually that requires being embedded with a military force in order to get to the places where civilians are trapped or trying to flee from."
What effect do you hope your work has on people?
"My first aim when covering a conflict is to act as a documentarian to create an unbiased record of what is going on, particularly the effect the war is having on civilians caught in its midst. That is something I know I can do and have control over. What that achieves is in many ways up to the viewer."
How concerned are you for your safety?
"I worry every minute when I am working in a conflict situation. It would be crazy if I didn't. It's important to listen to that worry because that is your natural limitation kicking in. If I am incredibly worried about a certain situation, it usually is for a good reason and that means I won't move forward. The challenge is to be constantly aware of that fear and decide how far you can push it. I only choose to continue working in conflict zones now while working for The New York Times because as an organisation they support me fully on the ground and we follow very strict protocols in order to mitigate the risk."
How do you cope with witnessing atrocities?
"It is important to take time off in the wake of a tough assignment to relax and let your mind rest. It can be very hard and requires a lot of discipline to get into a healthy routine when you come home. I do it with plenty of exercise, lots of sleep and eating well."
