Kevin Elphinstone Kevin Elphinstone  Associate Professor

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.

Engineers and Research Assistants

Corey Lewis Corey Lewis  Senior Proof Engineer

Corey is a senior proof engineer within the Trustworthy Systems group and is currently the lead engineer for verifying multi-core seL4. During his time at TS he has been involved in a wide variety of projects to do with seL4. These include developing the original CapDL translation tools, helping complete the information flow proofs, and contributing to the verification of the seL4 MCS extensions. His research interests include formal methods, functional programming, and program verification.

Jashank Jeremy Jashank Jeremy  Research Assistant; UNSW

Jashank is interested in programming languages as expressive aids for developing correct software; and in operating systems as fundamental infrastructure for developing robust and portable systems.

Jingyao Zhou Jingyao Zhou  OS Engineer

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

Michael McInerney  Senior Proof Engineer

Michael is currently working on verifying functional correctness for the MCS version of seL4.

Miki Tanaka Miki Tanaka  Senior Proof Engineer

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 currently is the technical lead of the verification of the seL4 MCS extensions.

Peter Chubb Peter Chubb  Senior Systems Consultant; Conjoint Senior Lecturer

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.

Ryan Barry Ryan Barry  Proof Engineer

Ryan is a software engineer who specialises in interactive theorem proving and concurrency theory. He is currently working on security proofs for the RISC-V architecture as part of the Time Protection project.

Siwei Zhuang Siwei Zhuang  Senior OS Engineer

Siwei works on low-level systems including operating system internals, device drivers, and embedded systems architecture.

Birgit Brecknell Birgit Brecknell  Project Manager

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


Gerwin Klein Gerwin Klein  Conjoint Professor; Founder and Chief Scientist at Proofcraft

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 Kuz Ihor Kuz  Conjoint Associate Professor; Engineer at Kry10

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 Andronick June Andronick  Conjoint Professor; Founder and CEO at Proofcraft

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 Kolanski Rafal Kolanski  Conjoint Lecturer; Founder at Proofcraft

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 Sison Robert Sison  Visiting Fellow; Research Fellow, University of Melbourne

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