My CV (January 2021)

I organize the Oxford Combinatorics Seminar. With Christina Goldschmidt, I run the online
Oxford Discrete Mathematics and Probability Seminar. All welcome!

I also organize the annual One-Day Meeting in Combinatorics in Oxford every May or June.
This year's meeting will take place on
**Tuesday 21 May 2024** (please note that this is different from the usual day; details about previous meetings can be found here). The meeting has been running since 1999, with a brief interruption for covid (in June 2021, I organized a special Round the World Relay in Combinatorics, with 22 seminars from around the world).
