Rob van Glabbeek has a strong international reputation in the study of the theory of concurrent computation, having made particular contributions to the conciliation of the interleaving and the true concurrency communities by codeveloping the current view of branching time and causality as orthogonal but interacting dimensions of concurrency. He condensed many divergent views on semantic equivalences into the linear time- branching time spectrum. The resulting publications are required reading in the graduate programs of several universities. Together with Peter Weijland he invented the notion of branching bisimulation, that since has become the prototypical example of a branching time equivalence, and the semantic equivalence used in most verification tools based on equivalence checking. With Ursula Goltz he proposed the notion of action refinement as a useful tool for evaluating semantic equivalences and implementation relations. This gave rise to a wave of publications, including a dozen Ph.D. theses. With Peter Rittgen he initiated the application of process algebraic methods in the formal description and analysis of economic production processes. As consultant for Ricoh innovations he contributed to the practical application of concurrency-theoretic ideas in workflow management. With Dominic Hughes he made a crucial contribution to the proof theory of linear logic by proposing a notion of proof net that had been sought after in vain by linear logicians with since the inception of linear logic. Together with Vaughan Pratt he initiated the now widespread use of higher dimensional automata and other geometric models of concurrency. With Gordon Plotkin he integrated various causality respecting models of concurrency, including Petri nets, event structures and propositional theories. With Wan Fokkink he used results from unification theory and from modal logic to obtain compositionality results in structural operational semantics. In 2007, in cooperation with Yuxin Deng, Matthew Hennessy, Carroll Morgan and Chenyi Zhang, he characterised the may- and must-testing preorders for processes with probabilistic and nondeterministic choice, thereby solving a problem that was posed in 1992 and has remained open ever since.

In addition, he has organised workshops on combining compositionality and concurrency, on logic, language and information, on the Unified Modelling Language, on workflow management, web services and business process modelling, on automatic and semi-automatic system verification, and on structural operational semantics. He is a member of the editorial boards of Information and Computation and Theoretical Computer Science and has been on several dozen program committees.

Research Interests

Associate Professor van Glabbeek’s research interests include: models of concurrency, compositional implementation relations, structural operational semantics, proof nets for linear logic, process algebra, temporal logic, and building a theory of processes with probabilities and nondeterminism.

Publications

Collaborations

Associate Professor van Glabbeek maintains close ties with the concurrency group at Stanford University and the Laboratory for Foundations of Computer Science at the University of Edinburgh. His work on proof nets and on concurrency modelling is to a large extent in cooperation with these groups. Van Glabbeek also participates in research activities in process algebra and structural operational semantics that span many European sites, including CWI, Aalborg University,and the University of Sussex. His work on hierarchical software development and on synchonous versus asynchronous communication is in cooperation with Professor Goltz at the University of Braunschweig.
