The School of Computing Science has a long history and tradition of outstanding programming language research. Across its research sections the School hosts a unique combination of world-leading researchers in programming languages research, broadly construed, ranging from foundational research into type systems, to the implementation of parallel runtime systems, to research into how people learn programming languages, naming but a few. Researchers in the Theme typically span theory and practice, with a strong emphasis on the development of practical tools.
The Programming Languages Theme allows researchers from all research Sections, at present including FATA, GLASS, and CCSE, with the aim of fostering cross-discipline collaborations. FATA hosts world-class researchers in the foundations of programming languages, with a particular focus on session types for concurrent and distributed systems (see here for an overview). GLASS has world-renowned experts in compilation, parallel and distributed computing. CCSE brings together a world-leading, interdisciplinary group of experts on Computing Science education research.
The PL Theme is supported by a lively seminar series, PLUG, held every two weeks during term time.
*NEW*: Members of the PL theme are organising Euro-Par'22, a major international conference on parallel and distributed computing, to be hosted at the University of Glasgow.
Theme Lead: Dr Ornela Dardha
Dr Gul Calikli's research field is empirical software engineering with a focus on human aspects. She conducts interdisciplinary research at the intersection of software engineering and cognitive psychology that is sometimes accompanied by Machine Learning (ML) techniques and social psychology theories. Part of her research focuses on program comprehension by designing user evaluations & program comprehension experiments.
José Cano Reyes is a Lecturer (Assistant Professor) in the School of Computing Science at the University of Glasgow and a visiting member of ICSA in the School of Informatics at The University of Edinburgh. His research interests are in the broad areas of Computer Architecture, Computer Systems, Compilers, Interconnection Networks, Machine Learning and Security. His current research is focused on hardware/software co-designed approaches to efficiently deploy Deep Learning applications on mobile/embedded edge devices (e.g. IoT boards, phones, drones, mobile robots).
Quintin’s origins are in programming language design and implementation in the context of persistent programming languages. Subsequently, he has been involved in programming education research, exploring many areas, including learners’ attitudes, program comprehension, assessment issues, conceptual development and PL transfer among near-novice programmers.
Dr Ornela Dardha is the founding director of the Concurrency Lab (CoLab) whose research focuses on using session types/typestates in formal models and programming languages for communication-safe distributed systems. She is an expert on the full spectrum of session types and typestates and PL research, from foundations to language design and software tool development, including formal modelling and tools for programming languages, such as Java and Scala.
Professor Simon Gay works on programming language foundations, especially session types for concurrent and distributed programming. He is currently leading the EPSRC project Stardust (Session Types for Reliable Distributed Systems) in collaboration with the University of Kent and Imperial College London.
Dr Lito Michala's research interests are predominantly application-driven large-scale information system architecture designs for the collection and processing of large amounts of data and the problems these introduce to scalability and reliability. Distributed computing and edge processing are able to address much of these issues.
Waqar’s research focus is on investigating tools and compilers for accessible heterogeneous computing, which involves working closely with a variety of languages and parallel programming frameworks. He is also interested in computing education research, where he’s been investigating work-based and competency-based learning, and also looking at ways to improve quality of CS education in developing countries.
Colin Perkins is a senior lecturer in the School of Computing Science, and the current chair of the Internet Research Task Force (https://irtf.org/). His research interests are on network transport protocols, with a particular focus on transport protocols for real-time and interactive multimedia for the Internet, and on improving the way we design, implement, specify, and standardise network protocols. He has a particular interest in the application of types and programming languages to improve network protocol standards, and on bringing together the network protocol standardisation and specification communities to produce systems that are useful to standards developers.
Dr Jeremy Singer's research interests are in compilers, cloud, managed run-times, parallelism, and resource management.

Mr Mathias Jakobsen's reserach iterests are in session types and typestates. He is currently working on aliasing control in object-oriented programming languages with typestate annotations.
Mr Thomas Koehler explores the design of rewrite-based optimising compilers that can adapt to new algorithms and hardware: domain-extensible compilers that provide an extensible set of program abstractions and optimisations.
Ms Ethel Tshukudu’s research is on conceptual transfer in programming languages. She specifically researches how relative novice programmers transfer conceptual and semantic knowledge from one programming language to the other. She is also currently working as a Research Assistant at Raspberry Pi Foundation. Her work involves conducting and managing individual and collaborative research projects in Computer Science Education.
Ms Uma Zalakain is interested in programming language theory, process calculi, type theory, and machine verification. She is working on machine verification of typed process calculi in Agda.
Mr Matthew Le Brun
Mr Matthew Le Brun’s research interests are in distributed systems and fault tolerance. He is a new PhD student exploring the links between formal logic, session types and fault-tolerance, and is researching methods of statically inferring fault-tolerance guarantees.

Glasgow, Haskell and the History of Functional Programming
Functional programming is a style of programming in which programs can be regarded as mathematical functions, with properties that make it easy to reason about programs' behaviour and correctness. Functional programming languages are characterized by elegant high-level constructs and clean theoretical foundations.
Beginning in 1987, the international research community in functional programming defined Haskell, a standardized functional programming language for research and teaching. Members of the Functional Programming Group in the Department of Computing Science played a leading role in the language design process. Development of the Glasgow Haskell Compiler began in 1990; it is still the leading implementation of the language, has tens of thousands of users, and hosts dozens of experimental language extensions. It is still under active development as an open source project.
The Journal of Functional Programming was launched in 1991, and continues to be the main journal in the area. John Hughes and Philip Wadler were among the founding editors; Simon Peyton Jones became an editor later; John Launchbury and John O'Donnell were members of the editorial board. During this period, the University of Glasgow was an internationally leading centre of functional programming research.
As a research topic, functional programming has been highly influential in the broader area of programming language theory, and Haskell in particular has been a hugely successful vehicle for the exploration of novel programming constructs, techniques and concepts. The involvement of the Glasgow group from 1987 to 1998 was a significant factor in this success.
We teach a range of more specilised courses related to PL, in addition to Level 1/2 CS courses. Below is a list.
- Distributed and Parallel Technologies H (COMPSCI4082)
- Functional Programming H (COMSCI4021)
- Programming Languages H (COMPSCI4016)
- Systems Programming H (COMPSCI4081)
- Theory of Computation H (COMPSCI4072)
