Current focus is on the following projects:
 Multicore seL4 Verification: We aim to provide frameworks for reasoning about concurrency in code for operating systems. In particular, our main project is to model and verify the multicore version of seL4.
 Formal Specification, Analysis and Verification of Mesh Protocols: We strive to develop methods and formalisms for protocol specification, analysis and verification. Amongst others we apply those methods and formalisms to routing protocols for wireless mesh networks, such as AODV, the Ad hoc Ondemand Distance Vector routing protocol. Additionally, we work on improvements of existing protocols and/or creation of new ones.
 Analysis of Protocols for Highassurance Networks: We aim to provide authentication and reliable communication protocols for unmanned aerial vehicles (UAVs). This covers both internal communication within the UAV and external communication between a ground station and the vehicle.
 Process Algebra: We study process algebraic languages and their semantics, in order to provide a firm theoretical basis for the specification, analysis and verification of concurrent systems.
 Asynchronous Communication in Distributed Systems: We aim to discover which systems can be implemented in a distributed way—and how—using only asynchronous communication between components, while preserving desirable properties that may be specified in terms of synchronous communication. In connection with this, we try to establish an expressiveness hierarchy of specification formalisms with different communication paradigms.
 Probability and Nondeterminism: The goal of this project is to build a theory of processes that faithfully integrates probabilities and nondeterminism.
