Prospective PhD Students & PostdocsI'm looking for PhD students, postdocs, and student programmers. See my research topics, research projects, and publications for an impression of my interests. See the PL group's open positions for what is available right now. Send me an email with CV and motivation/research interests, also to explore future opportunities.
Expressing IntentHow to enable software engineers to express intent directly in terms of the concepts of a domain of interest (and get the corresponding implementation for free)? Most of my (group's) research is related, one way or another, to that question, and includes: design of meta-languages for language design (to support the development of new languages), language theory and implementation techniques (such as parsing, name resolution, constraint solving, rewriting), design of domain-specific languages for particular domains (such as web programming, build systems, digital printers), evaluation of these languages in applications (such as WebLab, conf.researchr.org).
Declare Your Language with SpoofaxHow to enable software engineers to design and implement (domain-specific) programming languages? In the Spoofax Language Workbench project we explore solutions and integrate these in a programming environment for the development of languages using high-level declarative meta-languages for syntax, static semantics, dynamic semantics, program analysis, and program transformation.
Name Resolution with Scope GraphsHow to formalize the name binding rules of programming languages? We are developing scope graphs, a uniform framework for the representation of a wide range of name binding patterns in programming languages. A general theory of name resolution interprets scope graphs to resolve references to their corresponding declarations. Scope graphs are a core component of the Statix language for type system specification.
Incremental Software Pipelines with PIEHow to declaratively specify software pipelines for fine and coarse grained tasks and ensure their sound incremental execution? PIE is a domain-specific language and runtime for the specification of software pipelines and their incremental execution. PIE provides an expressive language for defining pipelines including dynamic dependencies, and guarantees efficient, precise and scalable incremental execution.
Programming Education at Scale with WebLabHow to scale programming education to large numbers of students? How to scale delivery of many assignments and exam questions for a course and still provide feedback to students? WebLab provides a web-based learning environment for programming education that supports lab assignments and proctored digital exams. WebLab is currently used in 25 courses at TU Delft, including a course on concepts of programming languages that got it all started.
In this course students study declarative meta-languages for compiler construction such as context-free grammars, scope graphs, type constraints, and strategic rewriting. Using this knowledge they build a compiler and IDE for MiniJava using the Spoofax language workbench.Master CS | CS4200 | Q1+Q2 | Info
Seminar Programming Languages

Web Programming Languages
In this course students study programming language facilities for web programming.Master CS | CS4275 | Q3 | Info
Language Engineering Project
In this course students explore (some aspect) of the design and implementation of a (domain-specific) programming language by building an implementation in Spoofax.Master CS | IN4333 | Q4 | Info
I supervise bachelor and master thesis projects in computer science at TU Delft. See my research areas to get an impression of my interests. Send me an email if you are interested in doing a project with me.Bachelor & Master CS | CSE3000, IN5000 | Q1-4 | Info
