Prof. Peter Dybjer is a leading researcher in type theory and constructive logic. He is widely recognised among other things for his influential work on inductive families, induction-recursion, and normalisation by evaluation.
After more than 40 years at Chalmers, Peter has now retired and been appointed Professor Emeritus.
To celebrate his lasting contributions we are organising a workshop on October 1st 2025 at Chalmerska huset.
