Short presentation
I am an assistant professor the Department of Information Technology at Uppsala University. My research primarily lies in the area of software testing with focus on security testing and network protocol testing. More broadly, I am interested in leveraging formal methods to analyze real-world software, particularly with respect to its security. Testing techniques I used include: automata learning, symbolic execution, model checking and grey-box guided fuzzing. For more info, check my website.
