I have been sporadically editing Wikipedia as an anonymous user since November 2004, and have become more involved since 2007. I have formal qualifications in physics, but I don't contribute much to physics articles anymore since most articles on topics I am familiar with are already so good that I feel there is little I can add. Instead, I try to improve areas that are still poorly covered by Wikipedia. My contributions are mainly in the areas of Economics, Transport, Geography, Technology, and Environment. I am also active in vandal fighting and article deletion.
