Aminu Bello Usman

Aminu Bello Usman serves as an Associate Professor of Computer Science and leads the Cybersecurity Research Group at York St John University's York Business School. His academic career spans international institutions including the University of Sunderland where he was Head of the School of Computer Science, and prior positions at Auckland University of Technology, NorthTech, and Bayero University, Kano. As a Senior Fellow of the Higher Education Academy (D3), he mentors academics across the UK through Advance HE.

Dr. Usman's research centers on critical cybersecurity challenges with particular focus on data privacy, IoT security, biometric authentication systems, applied artificial intelligence, and trust-based security mechanisms. His work emphasizes privacy-preserving models for healthcare applications, developing frameworks that integrate security from the ground up (Privacy by Design), and exploring trust dynamics in human-AI interactions, especially within culturally diverse contexts. His research bridges theoretical innovation with practical applications to address real-world security vulnerabilities.

His recent publications reveal a consistent trajectory toward securing healthcare IoT systems through biometric authentication, with significant emphasis on privacy preservation. His work spans multiple domains including quantum-inspired encryption for medical data, voice biometrics for IoT authentication, and chaos-based cryptographic approaches. The research demonstrates interdisciplinary convergence between cybersecurity, healthcare technology, and artificial intelligence, with growing attention to cultural dimensions of trust in security systems.
