About Me

I am a PhD candidate in Computer Science with a focus on Cybersecurity at Linköping University. My work focuses on trusted computing, secure software updates, and vulnerability analysis for computing systems, with outcomes published in peer-reviewed venues. Alongside research, I bring hands-on security practice (CEH, Security+), teaching and supervision experience, and practical development of web applications. I am pursuing my PhD under the supervision of Mikael Asplund.
