Trustworthy Systems

Gernot's main research interests are in operating systems, especially microkernel-based systems, and their use in embedded/cyber-physical systems, OS security and robustness issues, general cyber-security, energy/power management, real-time systems, virtualization and architectural support for operating systems.

Carroll's research is on formal methods, semantics, security, program correctness and probability.

Craig's research interests include type theory, logic, programming languages, compilers, and formal verification.

Johannes is interested in beauty and truth. Specifically, he works on interactive theorem proving, program verification and concurrency theory.

Kevin works on operating system microkernels and the infrastructure required to support larger systems upon them. His current focus includes secure embedded operating systems suitable for formal verification, and for being the basis of secure systems for embedded devices. He also has interests in componentised operating systems, operating systems in general, security, real-time systems, computer architecture as it pertains to operating systems, and virtualisation.

Scott works in the time protection team.

Zoltan, a non-standard analyst by training, works on the correctness proof for the seL4 kernel.

Alwin is working on optimising the IRQ and Exception fast paths in seL4.

Andy is working on improving the device driver framework.

Courtney works on secure multi-server operating system design.

Ivan is currently working to improve device drivers on seL4.

James is working to improve the locking in multicore seL4.

Jingyao is interested in real-time operating systems and hardware.

Lucy is working on the Device Driver Framework, to optimise device drivers running on seL4.

Miki is interested in formal verification techniques and their application to software systems, and broadly proof engineering as a discipline. Miki has contributed to the verification of architecture porting for seL4 and also the verification of the seL4 MCS extensions as the technical lead. Miki is currently involved in a project for device driver verification using the Pancake language (based on cakeML/HOL4).

Peter's research interests include operating system abstractions for, intra alia, storage, scheduling, memory management, and locking. He is also interested in capacity planning, and in systems performance measurement and optimisation. His main expertise is in Unix and Linux kernels, and low level system support built on these. He also maintains the Trustworthy Systems website and internal infrastructure.

Tiana is investigating a new systems language, 'pancake'.

Kevin's research is on creating a framework for reasoning about concurrent programs, with the ultimate goal of verifying multicore seL4.

Zilin's research is into functional programming, type theory, formal verification, compilers, and Embedded DSLs.

Mitchell is working on improving the seL4 Mixed-Criticality kernel model, with the aim to create a system with strong temporal isolation properties.

Patrick is working on applying seL4 to the automotive space.

Tom is working on hardware implementations of time protection.

Logic and automated theorem proving, metamathematics, programming language theory and formal methods.

Krishnan is working with Johannes on the pancacke language.

Birgit works part time with the TS group as project manager for strategic and external projects

Christopher is helping support the computer systems for the Trustworthy Systems group.

Tessa works part-time as the Administrative Assistant, managing the office. She works Mondays, Thursdays, and Fridays.

Gerwin's research interest is in Formal Methods, more specifically in interactive theorem proving, software verification, semantics of programming languages, and in the emerging field of proof engineering. Generally, he wants software systems to be dependable, and thinks that formal specification and proof can make a significant contribution towards that goal.

Ihor worked at TS from 2003 until 2021. During that time he led the systems team and many of the projects TS was involved with. He now works as an Engineer at Kry10.

Ihor's research interests include operating systems and distributed systems. In particular the design of flexible and modular operating systems, security and safety properties of such systems, distributed system middleware, and management of distributed resources.

June had joined the Trustworthy Systems research group in 2008 (in NICTA), and led the group from end of 2016 to end of 2020. Her main research interest is in formal verification and certification of software systems, more precisely in formal proof of correctness and security properties of programs using interactive theorem proving, as well as concurrency reasoning, targeting interruptible and multicore systems.

Rafal worked as a proof engineer at Trustworthy Systems until April 2021. He led the Proof Engineering team from 2016 until 2021.

Rafal is interested in the formal verification of high assurance, system-level software, both from the perspective of verification in practice, but also proof maintenance and increasing the proof coverage of already verified systems.

Robert is broadly interested in discovering how best to design and construct software systems with formally proved functional-correctness and security properties at scale. Their current research concerns the formal verification of operating systems to enforce increasingly useful forms of information-flow security, also known as confidentiality.
