About Hans-Dieter Hiep

In 2024, Hans-Dieter A. Hiep finished a Ph.D. program in Computer Science at Leiden University, Leiden Institute of Advanced Computer Science (LIACS) and Centrum Wiskunde & Informatica (CWI), cum laude. In 2018, he finished a Master program in Computer Science joint-degree at the Vrije Universiteit and Universiteit van Amsterdam (VU/UvA), cum laude, specializing in foundations of computing and concurrency. In 2016, he finished a Bachelor program in Computer Science, cum laude, also at the Vrije Universiteit.

His main academic interests are: formal methods and mathematical logic, higher-order logic and type theory, separation logic, program correctness (Hoare's logic and Reynolds' logic), and interactive and automated theorem proving. Other interests are: programming languages, cluster and grid computing, operating systems, computer networking, Java and Java virtual machines, reverse engineering, cyber security, distributed and concurrent algorithms, formal languages and automata, Web technologies, graphical user interfaces, and—in general—anything related to computer hacking.

Research projects

  • (Principal investigator) Verified Reowolf, funded by NGI ASSURE
    We research and develop a mathematical formalism, using the state-of-the-art theorem prover Coq, for the verification of properties of protocols specified in Protocol Description Language (PDL) that identify precisely under what conditions important properties, such as network integrity and service availability, remain to hold or when they break.
  • (Principal investigator) Reowolf II, funded by NGI POINTER
    Reowolf replaces the decades-old BSD-style socket for Internet communication: offering an innovative, programmable and interoperable connector API at the system-level to support the separation of concerns between privacy and performance optimization.
  • (Principal investigator) Reowolf, funded by NGI ZERO
    The Reowolf project aims to provide connectors as a generalization of BSD-sockets for multi-party communication over the Internet.
