Quantified computational effects and interaction *epartment of Computer Science, Reykjavik University One postdoc position Applications are invited for one postdoctoral position at the Department of Computer Science, Reykjavik University. The position is part of a three-year research project funded by the Icelandic Research Fund under the direction of Tarmo Uustalu. The overarching goal of to advance the theory and practice of disciplined effectful programming, based on graded monads, monad-like structures and interaction laws.
