Thierry Coquand, professor at the University of Gothenburg, had his 60th birthday on 18 April 2021. We are organizing this scientific meeting to celebrate him and his seminal contributions to mathematical logic, constructive mathematics, theoretical computer science, and the development of proof assistants for type theory. The celebration was originally planned to take place in direct connection with Thierry’s birthday, but had to be postponed several times because of the pandemic. 

The meeting will take place in Gothenburg on 24–26 August 2022, and is open to everyone who wants to join the celebration. It is free of charge, except that participants who wish to join the banquet in the evening on Thursday 25th of August have to pay their bill directly to the restaurant. Participants are also asked to arrange their own travel and accommodation.
