One way of characterising my research is to take a chronological view. This may - or may not - reveal a continuity of thought, or at least a common theme or perspective. This can, of course, also with some effort be inferred from the list of publications. The topics indicated below are ones where I have been fortunate enough to make some kind of contribution, often in collaboration with others and always with the inspiration from ideas that in one way or another came to, or were brought to, my attention. of
