On this page you can find a list of the talks I have given along with links to slides and/or videos where available. Many talks do not have video links because they were not all recorded. Some do not have slide links because I sometimes prefer to use the blackboard, there was a time in the distant past when people used to write their slides by hand on transparencies, and some slides have not yet been converted from obsoltete file formats. They may be added when I get round to it, but do not hold your breath.
