And can you tell me a little bit about your PhD topic?

Sure. I did my PhD in a philosophy department. It was a kind of crossover topic between environmental ethics and political philosophy. I was looking at the ethics underneath resource management law so what should and shouldn't people be allowed to do with their property when that property is environmentally sensitive. I spent a lot of time in the 17^th century looking at John Locke and asking the question, 'What does this all mean?' in a world where the environment is actually an issue in a way that it wasn't back then.
