Pramod Bhatotia, who completed his doctoral studies at MPI-SWS, has received the 2023 EuroSys Jochen Liedtke Young Researcher Award.

The EuroSys Jochen Liedtke Young Researcher Award was created in 2014 by ACM EuroSys to reward junior European researchers who have demonstrated exceptional creativity and innovation in systems research, broadly construed. The award is given annually at the EuroSys conference, in memory of Jochen and his fundamental contributions to the systems community. The award is accompanied by a 2,000 EUR cash prize generously provided by RedHat.

Congratulations, Pramod!

MPI-SWS faculty member Viktor Vafeiadis has received the 2022 Robin Milner Young Researcher Award, which is given by ACM SIGPLAN to recognize outstanding contributions by young investigators in the area of programming languages.  The award citation reads as follows:

"Viktor has become a world leader in semantics and verification research. His body of work includes fundamental and influential contributions to the study of concurrency, in particular separation logic and relaxed memory models. His landmark doctoral thesis developed RGSep, the first extension of concurrent separation logic to support formal proofs about fine-grained concurrent algorithms.  His work on Cave presented the first fully automatic verifier for establishing linearizability of a class of concurrent data structures, including ones with non-fixed linearization points. His work on CompCertTSO presented the first verified compiler for a concurrent language under a relaxed memory model. He developed the first direct (and mechanized) proof of soundness for concurrent separation logic (CSL) based on operational semantics—beautifully simple compared to prior proofs and a key enabler for proving soundness of more advanced program logics like CAP and Iris. He developed the first separation logic for the C/C++ relaxed memory model—a tour-de-force achievement compared to the standard CSL which assumes sequential consistency. This spawned a whole body of work on modular verification of concurrent data structures under relaxed memory models. His work has found and corrected a number of serious flaws in the C/C++ concurrency model, which led to changes in the C++ standard. And his "promising" semantics for relaxed-memory concurrency offered one of the first viable solutions to the 30-year-old "out-of-thin-air" problem and spawned much follow-on work. His work on GenMC presented the first efficient model checkers for relaxed-memory C/C++ programs with optimality guarantees about their state space exploration. Recent work together with his postdoc Azalea Raad (now faculty at Imperial), presented the first "persistency semantics" for non-volatile memory on multicore architectures. Viktor is not only highly-cited and incredibly prolific—he is also a true pioneer, repeatedly exploring dauntingly technical problems in the semantics and verification of concurrent programs before others dare to try."

This award makes MPI-SWS the only institution in the world to boast two recipients of the SIGPLAN Milner award among its faculty.

Bob Harper, an MPI-SWS external scientific member, has received the 2021 ACM SIGPLAN Programming Languages Achievement Award---the most significant international career award in programming languages. He received the award for his "foundational contributions to our understanding of type theory and its use in the design, specification, implementation, and verification of modern programming languages".

Award Citation:

Robert (Bob) Harper is widely known for his foundational contributions to our understanding of type theory and its use in the design, specification, implementation, and verification of modern programming languages. Bob demonstrated that sound type systems and operational semantics are not only appropriate vehicles for reasoning about idealized languages, but that this theory can be applied to complex, modern languages. His achievements include analysis of language features ranging from references to continuations to modules, the definition of a variety of new type systems, the idea of using types throughout the compilation process, the analysis of run-time system semantics and cost, a formal definition of Standard ML and its mechanization, the definition of logical framework LF and other logical frameworks based on homotopy type theory.

Some of Bob’s most influential work involved the design, theory and implementation of the TIL (Typed Intermediate Language) compiler system, which pioneered the idea that compilers can propagate type information to lower-level intermediate languages, where it can be used to guide optimizations and to catch compiler bugs. These ideas led directly to the development of proof-carrying code, typed assembly language, and a wide array of type-preserving compilers.

Bob Harper has also had a profound impact though his mentorship, teaching and the influence of his books “Programming in Standard ML” and “Practical Foundations for Programming Languages.”

MPI-SWS faculty member Derek Dreyer has received the 2017 Robin Milner Young Researcher Award, which is given by ACM SIGPLAN to recognize outstanding contributions by young investigators in the area of programming languages.  The award citation reads as follows:

"Derek Dreyer has made deep, creative research contributions of great breadth. His areas of impact are as diverse as module systems, data abstraction in higher-order languages, mechanized proof systems and techniques, and concurrency models and semantics. He has refactored and generalized the complex module systems of SML and OCaml; devised logical relations and techniques that enabled advances in reasoning about higher-order imperative programs; and developed novel separation logics for modular verification of low-level concurrent programs. His research papers are a model of clarity and depth, and he has worked actively to translate his foundational ideas into practice – most recently with the RustBelt project to provide formal foundations for the Rust language. Additionally, Dreyer has contributed leadership, support, and mentorship in activities such as the PLMW series of workshops, which are instrumental in growing the next generation of PL researchers."

Previous recipients of the award have included Stephanie Weirich, David Walker, Sumit Gulwani, Lars Birkedal, and Shriram Krishnamurthi.

MPI-SWS faculty Peter Druschel has been honored as the eighth recipient of the Mark Weiser Award -- the top international award in the field of operating systems.

The Mark Weiser Award was established in 2001 by ACM's Special Interest Group on Operating Systems. Recipients must have begun their careers no earlier than 20 years prior to nomination, and they are selected based upon "contributions that are highly creative, innovative, and possibly high-risk, in keeping with the visionary spirit of Mark Weiser."

In the award ceremony, Peter's broad and high-impact contributions in his research field were highlighted, including work such as the Pastry peer-to-peer system, the Flash web server, the Fbufs operating system support for high-speed networking, and his work on resource management in large-scale servers.

Peter received his Ph.D. from the University of Arizona in 1994. He was a Professor of Computer Science at Rice University, before accepting his current position as the founding director of the Max Planck Institute for Software Systems.

Previous recipients of the Mark Weiser Award are Frans Kaashoek (MIT), Mendel Rosenblum (Stanford), Mike Burrows (Google), Brian Bershad (Univ. of Washington), Tom Anderson (Univ. of Washington), Dawson Engler (Stanford), and Peter Chen (Univ. of Michigan)
