--- title: Ralf Jung ---

I am a post-doctoral researcher in the PDOS group at MIT CSAIL under the supervision of Frans Kaashoek and Nickolai Zeldovich.
Previously, I completed my PhD at MPI-SWS and Saarland University in Saarbrücken, Germany; my advisor was Derek Dreyer.

I will start my position as assistant professor at ETH Zürich on November 1st. If you are interested in doing a PhD or post-doc working on programming language foundations, and in particular formal foundations for Rust, or if you are an ETH student interested in a Master Thesis in that area -- please [reach out](https://research.ralfj.de/contact.html)!

My two main lines of work are about Rust and Iris.
On the Rust side, I am working (also in collaboration with the Rust language team) towards a solid formal foundation for the language, including in particular the unsafe parts. One key result here is our type safety proof, which also describes a methodology for establishing type safety of well-encapsulated unsafe code. My goal is to make unsafe Rust just as safe as safe Rust by means of formal verification.
On the Iris side, besides continuing development of its logical foundations, I am interested in applying Iris to new problem domains; recently I started working on modular verification of fault-tolerant distributed system components.

In my free time, I like to run internet services myself and work on free software. This goes hand-in-hand with my pursuit of defending our privacy rights and our freedom in the digital world. See my personal website for more information.
