Seminars
The following is a mostly complete list of the seminars that I have given, both in my home universities and elsewhere. They are split into two groups: the first consists of all seminars that I have given that are not Kinderseminars (junior seminars in Oxford); and the second group consists of the Kinderseminars. By clicking on the title you may access (where available) the transcript or slides that accompanied the talk, and in the case of Banff a video of the talk. If both are available, then the second follows the title in brackets.
Note that, due to family commitments, I am currently reducing my travel, and so I have given very few seminars and talks at conferences in recent years.
