I am an elderly English male, involved in public policy on transport, energy and the environment for many years. I have only recently started editing Wikipedia articles, and am still feeling my way both technically and in judging the right level. I plan to focus initially on topics connected with sustainable transport policy, especially where there is a substantial research and evidence base which is not widely known. I would also like to start a series of summary biographies of the academics and other professionals who have constructed this evidence base.
