I’m interested in the systems people rely on, and what it takes to keep them resilient and trustworthy.
My research applies machine learning and privacy-preserving computation to malware and cyberattack detection in devices, cyber-physical systems, and connected IoT.
My path began in electrical engineering at the University of Nigeria, Nsukka, and took me through security roles at Zinox Technologies and Standard Bank in Lagos. I completed my MSc in Cyber Security at Edge Hill University with distinction, followed by a CyberASAP research associateship at the University of East Anglia.
