Process Algebra
 Aim: study process algebraic languages and their semantics, in order to provide a firm theoretical basis for the specification, analysis and verification of concurrent systems
 Context: Process algebra is an algebraic approach to the study of concurrent processes. Its tools are algebraic languages for the specification of processes and the formulation of statements about them, together with calculi for the verification of these statements.

Activities
 AWN, a process algebra for wireless mesh networks: We development a new process algebra that enables us to formalise routing protocols for wireless mesh networks.
 Structural operational semantics: We aim to derive congruence properties for suitable equivalences and refinement preorders, through syntactic requirements in operational specifications of processes.
 Process algebras with probabilistic as well as nondeterministic choice: We study the addition of probabilistic choice to the process algebra CSP.
 Expressiveness of process calculi: We propose and elaborate a definition of what it means for one process calculus to encode another one, thereby enabling an ordering of process calculi with respect to expressive power. Our definition requires a process to be behaviourally equivalent with its encoding, and thus is parametrised with the choice of a suitable semantic equivalence on processes. By means of a series of case studies we hope to ascertain which semantic equivalences are most suitable for certain applications. Finally, we hope to apply the framework to compare the expressiveness of existing process calculi, in particular focussing on calculi with synchronous and with asynchronous communication primitives.
