Klaus von Gleissenthall

I am a tenured Assistant Professor in Computer Science at the Vrije Universiteit Amsterdam, where I am affiliated with the theory group and VUSec.

I work on methods that help practitioners write correct, secure and reliable systems, where I focus on keeping user effort low. My research interests span programming languages, security and systems.

Here is my CV.

Send me an email here.

I'm also archiving my application material from 2020: Research Statement and Teaching Statement.

Open Positions: I'm looking for students at all levels. I have open positions for PhDs, and post-docs. If you're interested in the intersection of Security, Programming Languages and Formal Verification, please email me.

Bio

Before coming to the VU, I was a post-doc in the Programming Systems group at UCSD where I worked with Ranjit Jhala and Deian Stefan. Before that, I was a PhD student at TUM where I was advised by Andrey Rybalchenko and funded through a Microsoft Research scholarship. During my PhD I worked at Microsoft Research Cambridge as an intern and spent some more time there as a visitor. I received both a BSc. and MSc. in computer science from TUM with a minor in logic and philosophy of science at LMU. During my master's, I spent five months at Université Paris Diderot.
