Christopher Pulte

Christopher Pulte serves as a Royal Society University Research Fellow and Affiliated Lecturer in the Computer Laboratory at the University of Cambridge, where his work bridges theoretical computer science and practical systems verification. His research specifically targets the verification challenges of low-level systems software where hardware concurrency models complicate correctness proofs.

His educational foundation includes:

• PhD in Computer Science from University of Cambridge (supervised by Peter Sewell)
• Master's degree from University of Cambridge
• Undergraduate studies at Technical University Dortmund

Pulte's research program focuses on developing formal methods for systems software verification, particularly through programming language semantics and type systems. He investigates how to reason about concurrent systems under relaxed memory models (ARM, RISC-V), creating frameworks that make verification tractable for security-critical components like hypervisors. His approach combines executable semantics with refinement typing to handle real-world complexity while maintaining mathematical rigor.

Analysis of his publication trajectory reveals consistent innovation in formalizing processor memory architectures and building verification tools that scale to production systems. His work demonstrates increasing emphasis on practical applications, notably through verification of Google's pKVM hypervisor components, while maintaining strong theoretical foundations in separation logic and concurrency semantics.

His scientific recognition includes:

• Royal Society University Research Fellowship

Pulte actively contributes to Cambridge's academic mission through teaching core computer science courses including 'Hoare Logic and Model Checking' for Part II students and guest lectures on 'Multicore Semantics and Programming'. He leads development of practical verification tools like CN (for C systems verification) and rmem (for memory architecture modeling), which have gained adoption in both academic and industrial research contexts through open-source distribution.

As part of the Computer Laboratory's Systems Research Group, he collaborates extensively with Peter Sewell's team on the REMS project, focusing on executable specifications for hardware/software interfaces. His current work extends these foundations to emerging architectures while improving the usability of verification frameworks for systems developers.
