7 <p>I am a post-doctoral researcher in the <a href="https://pdos.csail.mit.edu/">PDOS group</a> at <a href="https://www.csail.mit.edu/" target="_blank">MIT CSAIL</a> under the supervision of <a href="https://people.csail.mit.edu/kaashoek/" target="_blank">Frans Kaashoek</a> and <a href="https://people.csail.mit.edu/nickolai/" target="_blank">Nickolai Zeldovich</a>.<br>
8 Previously, I completed my <a href="thesis.html">PhD</a> at <a href="https://www.mpi-sws.org/">MPI-SWS</a> and <a href="https://www.uni-saarland.de/" target="_blank">Saarland University</a> in Saarbrücken, Germany; my advisor was <a href="https://people.mpi-sws.org/~dreyer/">Derek Dreyer</a>.</p>
10 <p><i>I will start my position as assistant professor at ETH Zürich on November 1st.
11 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)!</i></p>
13 <p>My two main lines of work are about <a href="https://www.rust-lang.org/">Rust</a> and <a href="https://iris-project.org/">Iris</a>.<br>
14 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.
15 One key result here is our <a href="https://plv.mpi-sws.org/rustbelt/popl18/">type safety proof</a>, which also describes a methodology for establishing type safety of well-encapsulated unsafe code.
16 My goal is to make unsafe Rust just as safe as safe Rust by means of formal verification.<br>
17 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.<br>
