Ulf Kargén

Assistant Professor

My main research interests lie within the areas of software security and software testing.

I am an Assistant Professor at the Department of Computer and Information Science at Linköping University. My research broadly focuses on ensuring safety and security of software. I also teach several courses related to cyber security.

I received my PhD in Computer Science from Linköping University in 2019 on the topic of dynamic analysis of machine code programs. I have a broad interest in topics related to system and software security and software testing. Some of my recent research has focused on estimating the risk of so-called ROP attacks against software, and on safety testing of autonomous vehicles.
