-<p>I am a PhD student at <a href="http://www.mpi-sws.org/" target="_blank">Max Planck Institute for Software Systems (MPI-SWS)</a> and <a href="http://www.uni-saarland.de/" target="_blank">Saarland University</a> under the supervision of <a href="http://www.mpi-sws.org/~dreyer/" target="_blank">Derek Dreyer</a>, head of the <a href="http://plv.mpi-sws.org/" target="_blank">Foundations of Programming group</a>.</p>
+<p>I am assistant professor at <a href='https://ethz.ch' target="_blank">ETH Zürich</a>, leading the <a href="https://plf.inf.ethz.ch/" target="_blank">Programming Language Foundations Lab</a>.
+We are part of the <a href='https://pls.inf.ethz.ch/' target="_blank">Institute for Programming Languages and Systems</a>.</br>
+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>.
+I also did a post-doc 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>.

-<p>Previously, I did my Bachelor's thesis in computer science at the <a href="http://www.cdl.uni-saarland.de/index.php">Compiler Design chair</a> of the university (also see below).</p>
+<!-- <p><i>I am offering up to two fully funded PhD positions in my newly founded research group at <a href="https://ethz.ch/en/the-eth-zurich/working-teaching-and-research.html">ETH Zürich</a>, with flexible start date.
+I am looking for strong students that want to do research at the foundations of programming language theory, in program verification and separation logic, with a focus on Rust and Iris.
+Knowledge of Coq is greatly appreciated. Interested candidates can <a href="contact.html">contact me directly</a>.
+Please explain why you are interested in a PhD in this field and what your prior experience is. Also include a CV and possible contacts for recommendation letters.
+Note that doing a PhD at ETH Zürich generally requires a Master's degree, but there is a <a href="https://inf.ethz.ch/doctorate/direct-doctorate-computer-science.html">direct doctorate program</a> that you can enter with a Bachelor's degree (application deadline December 15th).</i></p> -->
-<p>I am currently working on giving a formal model to <a href="https://www.rust-lang.org/">Rust's</a> type system.
-This builds on my previous work on a logic to support modular reasoning about higher-order concurrent imperative programs. The focus there was on providing simple building blocks that are powerful enough to recover more sophisticated reasoning techniques that were often axiomatized in previous logics. <br/>

+<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>
+On the Rust side, me and my group are working (also in collaboration with the Rust language team) towards a solid formal foundation for the language, including in particular the unsafe parts.
+As part of this we are developing <a href="https://github.com/rust-lang/miri/">Miri</a>, a practical tool for detecting Undefined Behavior bugs in unsafe Rust code, which has become a part of the standard toolbox of unsafe code authors.
+Meanwhile, <a href="https://github.com/minirust/minirust">MiniRust</a> is our work-in-progress proposal for a precise specification of unsafe Rust, that I hope to integrate into an official Rust specification eventually.
+My long-term goal is to make unsafe Rust just as safe as safe Rust by means of formal verification based on rigorous foundations for all key components of the language.<br>
+On the Iris side, I am continuing development of its logical foundations.
+We are making Iris fit for specifying and verifying programming languages at scale using a more modular approach.
+The long-term goal is for Iris to be able to handle the full scale of complexities that arise when doing foundational verification of real languages.<br>
