About

Alexandre Joannou is a leading researcher in computer architecture and security, with a primary focus on capability-based memory protection for embedded systems. His most influential work, "CheriRTOS: A Capability Model for Embedded Devices" (2018, 20 citations), introduces a transformative approach to defending connected embedded devices—used across automotive, medical, robotics, and avionics sectors—against sophisticated cyberattacks. By integrating CHERI (Capability Hardware Enhanced RISC Instructions) capabilities into a real-time operating system, Joannou demonstrates how fine-grained memory protection can be achieved without sacrificing performance, addressing the critical security vulnerabilities that arise as embedded systems become increasingly networked. This contribution is foundational to the broader CHERI ecosystem, which aims to fundamentally redesign how memory safety is enforced at the hardware-software interface. Joannou’s work is particularly impactful for researchers and engineers seeking practical, deployable solutions to the growing attack surface of the Internet of Things, and his research continues to influence secure system design in safety-critical domains.
