About
With 8+ years in cybersecurity and privacy, I'm a passionate researcher committed to advancing security and resilience. Proficient in security frameworks, compliance, risk assessment, threat intelligence, and machine learning, I specialize in network and cloud security technologies.
Currently, I'm a cybersecurity researcher at NTNU's Critical Infrastructure Security and Resilience (CISaR) group, contributing to the EU-funded CYBERUNITY (Community for Integrating and Opening Cyber Range Infrastructures that Build an Interoperable Cross- Domain and Cross-Sector Cyber Range Federation) project. Certified in CISSP, CCSP, and Microsoft Azure Security (SC-100/200/300, AZ-500), I'm enthusiastic about expanding my skills and knowledge in cybersecurity.
