Research Interest

My research focuses on formal hardware models for complex heterogeneous platforms. I am a member of the Sockeye project which aims to find abstractions for the hardware/software interface that have formal semantics to tackle the complexity of modern hardware.

Within that space my main interest is in trustworthy platform management. I work on formally modeling power topologies and developing tools that use the models to correctly and reliably manage the complex power distribution networks on modern computer systems [1]. This also entails research into how to specify chip-to-chip protocols like I2C [2] and generating drivers and hardware designs from the specifications. The main platform for experimenting with these ideas is the Enzian research computer, a heterogeneous server class platform for systems software research we built in the Systems Group at ETH Zurich. I lead the project to create a trustworthy Baseboard Management Controller stack for the platform.

I was also a member of the Barrelfish OS team, working on integrating information from formal hardware models into the OS. As my Master’s thesis I designed a specification language to describe address translation hardware in a modern computing system. The language is called Sockeye and has since taken on a bit of a life on its own outside the Barrelfish project. We are now using an improved version of the language to analyze the trust relationships between components in SoCs [3].
