Alexandru Baltag is an Associate Professor at the Institute for Logic, Language and Computation (University of Amsterdam). He is known mostly for his work in logics for multi-agent information flow (- he was one of the originators of dynamic epistemic logic) and their applications to communication, game theory, epistemology etc. He also worked on non-wellfounded set theory, coalgebraic logic, logics ...

He received his PhD in Mathematics in 1998 at Indiana University under the supervision of Jon Barwise. Between 1998 and 2001, he was a post-doctoral researcher at the Dutch Center for Mathematics and Computer Science. Between 2001 and 2011 he was a University Lecturer at Oxford University, in the Department of Computer Science. Sonja Smets is an associate professor at the Institute for Logic, Language and Computation at the University of Amsterdam. She obtained her PhD at the Free University of Brussels in 2001 and after a post-doctoral research position at the Flemish Fund for Scientific Research, she was a lecturer at the Free University of Brussels till 2009. In 2009 she worked as an assistant professor with a Rosalind Franklin Research Fellowship at both the Faculty of Philosophy (Dept. Theoretical Philosophy) and the Faculty of Mathematics & Natural Sciences (Multi-agent Systems Group in Artificial Intelligence) at the University of Groningen. In 2009, she received a VIDI award and in 2011 she received and ERC starters grant. Her research programme ranges over Logic (in particular non-classical logics, including non-monotonic logics, belief revision, modal and temporal logic, quantum logic); Multi-agent Systems; Formal Epistemology; Philosophy of Science, Philosophy of Quantum Physics, Quantum Information and Computation.
