What I work on

Research

My work sits between hardware and data: building connected sensing systems, securing them, and turning what they measure into something reliable.

IoT Cybersecurity & Moving Target Defense

Defenses that make connected devices a harder, moving target. My Moving Target Defense strategy randomly shuffles the communication protocols an IoT node uses to reach its gateway, disrupting an attacker's reconnaissance without degrading the system's performance.

Environmental sensing at city scale

Low-cost IoT networks that measure the world around us. At Queen Mary University of London I design and deploy an air-quality monitoring network across the Mile End campus, from the sensor hardware to the edge processing and analysis of the data it produces.

Air quality · sensor networks · edge computing · time-series data

Connected systems, networks & embedded testbeds

The building blocks underneath: wireless testbeds for IoT, sensor networks for precision agriculture, and earlier hardware projects, from a body-powered phone charger to EEG-driven robotics.
