MPI-SWS offers a vibrant, dynamic, multi-cultural environment for research and education. We have openings for both graduate students and postdoctoral research scholars.

Graduate students work as members of one or more of the institute's research groups, which perform internationally leading, highly visible research in their respective fields of specialization. Graduate students receive individual training and mentorship from MPI-SWS faculty, preparing them for leadership positions in academic or industrial research.

Postdoctoral Fellows have the opportunity to work with MPI-SWS faculty on existing lines of research, as well as develop their own research agenda under MPI-SWS faculty supervision.

Derek Dreyer, head of the MPI-SWS Foundations of Programming group, has been awarded an ERC Consolidator Grant. Over the next five years, his project "RustBelt: Logical Foundations for the Future of Safe Systems Programming" will receive almost 2 million euros, which will allow the group to develop rigorous formal foundations for the Rust programming language.

The European Research Council (ERC) is a pan-European funding body that supports cutting-edge research. It offers funding for groundbreaking research projects of the highest scientific quality across Europe, across all research areas. Talented researchers from all over the world can receive funding for excellent research in Europe. The ERC Consolidator Grant offers funding for researchers with 7 to 12 years of experience after achieving a PhD.

The RustBelt Project

A longstanding question in the design of programming languages is how to balance safety and control. C-like languages give programmers low-level control over resource management at the expense of safety, whereas Java-like languages give programmers safe high-level abstractions at the expense of control.

Rust is a new language developed at Mozilla Research that marries together the low-level flexibility of modern C++ with a strong "ownership-based" type system guaranteeing type safety, memory safety, and data race freedom. As such, Rust has the potential to revolutionize systems programming, making it possible to build software systems that are safe by construction, without having to give up low-level control over performance.

Unfortunately, none of Rust's safety claims have been formally investigated, and it is not at all clear that they hold. To rule out data races and other common programming errors, Rust's core type system prohibits the aliasing of mutable state, but this is too restrictive for implementing some low-level data structures. Consequently, Rust's standard libraries make widespread internal use of "unsafe" blocks, which enable them to opt out of the type system when necessary. The hope is that such "unsafe" code is properly encapsulated, so that Rust's language-level safety guarantees are preserved. But due to Rust's reliance on a weak memory model of concurrency, along with its bleeding-edge type system, verifying that Rust and its libraries are actually safe will require fundamental advances to the state of the art.

In this project, we aim to equip Rust programmers with the first formal tools for verifying safe encapsulation of "unsafe" code. Any realistic languages targeting this domain in the future will encounter the same problem, so we expect our results to have lasting impact. To achieve this goal, we will build on recent breakthrough developments by the PI and collaborators in concurrent program logics and semantic models of type systems.

Joel Ouaknine joins the institute's faculty as a scientific director, effective Aug 1, 2016. Joel's research interests include the automated verification of real-time, probabilistic, and infinite-state systems (e.g. model-checking algorithms, synthesis problems, complexity), logic and applications to verification, decision and synthesis problems for linear dynamical systems, automated software analysis, concurrency, and theoretical computer science.

In 2015, Joel was awarded an ERC Consolidator Grant, which provides almost 2 million euros of research funding over a period of five years. He is also the recipient of the 2010 Roger Needham Award, given annually "for a distinguished research contribution in Computer Science by a UK-based researcher within ten years of his or her PhD."

Joel will join MPI-SWS from the University of Oxford, where he is a Professor of Computer Science and Fellow of St John's College. Joel holds a BSc and MSc in Mathematics from McGill University, and received his PhD in Computer Science from Oxford in 2001. He subsequently did postdoctoral work at Tulane University and Carnegie Mellon University.
