Bio
Samuel Wairimu is a researcher in Computer Science at the Department of Mathematics and Computer Science, Karlstad University. He earned his doctorate in Computer Science in 2024. His doctoral research was part of the DHINO project, where he focused on the security and privacy for digital health and assessing privacy risks and harms to users.
Before his doctoral studies, Samuel completed a Master's degree in Cybersecurity at the University of Chester, UK, in 2019. He focused on information security, including ISO 27001, ethical hacking, digital forensics and incident response, and software exploitation. His dissertation addressed mitigating code-reuse attacks, specifically, Return-Oriented Programming (ROP).
