The School of Computer Science at the University of St Andrews has a fully-funded scholarship available working with Dr Areti Manataki. The PhD topic is “Shedding light on patient flow through advanced data visualisation”. Applications must be received by 1 March 2023.
In modern healthcare systems, millions of patients are admitted to hospital every day. Managing patient flow through hospital, to ensure that patients are at the right place at the right time, can improve quality of care and health outcomes, while saving money and time. However, managing patient flow in a way that is safe for patients and cost-efficient is a challenging task, and requires a deep understanding of the complexities associated with patient flow.
This project involves employing advanced data visualisation techniques to shed light on patient flow and its many important dimensions: temporal and spatial patterns, patient characteristics, clinical expertise, hospital capacity and associated cost. Drawing inspiration from visualisation approaches to astronomy and transportation, and working closely with healthcare professionals, we will develop interactive visualisations that allow for the exploration of large and rich patient flow data. Our aim is to build visualisations that are powerful enough to capture the complexity of patient flow, and, at the same time, simple enough for clinicians to easily use to draw conclusions towards improving care.
We are looking for highly motivated research students willing to be part of a diverse and supportive research community. Applicants must hold a BSc or MSc in Computer Science or a related area (e.g., Data Science, Engineering, Mathematics, etc.). Experience in data visualisation, enthusiasm for research at the intersection of data science and health, an ability to think and work independently, excellent programming and analytical skills, and strong verbal and written communication skills are essential.
International applications are welcome. We especially encourage female applicants and underrepresented minorities to apply.
Informal inquiries can be directed to Dr Areti Manataki at A.Manataki@st-andrews.ac.uk. Formal applications can be made through the School’s postgraduate research portal.
The deadline for applications is 1 March 2023.
We have one fully-funded scholarship available, which will be awarded competitively to the best applicant. This scholarship covers all tuition fees irrespective of country of origin and comes with a stipend (currently £17,668 per annum full-time equivalent). Additional scholarships may be available from other sources.
The School welcomes applications from under-represented groups, and is willing to consider part-time and flexible registrations. The successful applicant will however be expected to conduct their research in St Andrews and not fully remotely.
Dr Alan Miller and Catherine Anne Cassidy of the Open Virtual Worlds research group have been successful in funding from the Impact Innovation Fund for their project “Evidencing and Amplifying Impact of Immersive Exhibits in Highlands and Islands Museums”. The project will evaluate the value of digital heritage engagement with virtual reality exhibitions and further develop opportunities to preserve and promote cultural heritage in the highlands and islands of Scotland. Collaborative activities and approaches trialled are intended to discover ways to maximise positive impact. Exhibits are part of the Northern Heritage Network, which provides an infrastructure for transnational collaboration of heritage organisations to preserve and promote heritage within and beyond the North Sea region. The geographical focus of the network is: Finland, Sweden, Norway, Denmark, Scotland, Island of Ireland, Faroe Islands, Iceland, Greenland and the Baltic countries.
Lockdown and COVID-19 meant that the focus of the heritage sector was how to connect with audiences remotely. Whether this be through live online events, social media, virtual tours or other means. In the coming year there is much emphasis on sustainability and on the return of visitors to museums.
Evidence prior to COVID-19 shows that such exhibits have a positive impact in: communicating heritage, improving the sustainability of museums, improving visitor numbers and contributing to the wider Scottish economy. This is recognised by museums who are setting aside valuable space, and time to host immersive exhibits in the coming year. Through developing, deploying and using immersive exhibits we will enhance the “within walls” museum experience with the following impacts:
Design of a Heritage Impact Toolkit for digital heritage engagement evaluation will facilitate relevant data collection for West Highland Museum, Timespan Museum, Tomintoul & Glenlivet Discovery Centre, North Isles Landscape Partnership Scheme, Finlaggan Trust, Museum of Islay Life, and Comann Eachdraidh Uibhist a Tuath.
Through surveys, interviews and observation we will collect evidence of impact. Identified profiles for evidence collection include end users (visitors), stakeholders (community), museum and visitor centres (heritage practitioners), and third party organisations (e.g., Creative Scotland, European Commission, ICOM), This will be combined with statistics including visitor numbers and feedback from visitors. Inquiry will cover:
We had our first School seminar of the semester today. The speaker was André G. Pereira visiting Scotland on a SICSA DVF Fellowship. André is working on AI Planning problems, an area that is closely related to the work of our own Constraint Programming research group.
Title: Understanding Neuro-Symbolic Planning
Abstract: In this seminar, we present the area of neuro-symbolic planning, introducing fundamental concepts and applications. We focus on presenting recent research on the problem of learning heuristic functions with machine learning techniques. We discuss the distinctions and particularities between the “model-based” and “model-free” approaches, and the different methods to address the problem. Then, we focus on explaining the behavior of “model-free” approaches. We discuss the generation of the training set, and present sampling algorithms and techniques to improve the quality of the training set. We also discuss how the distribution of samples over the state space of a task, together with the quality of its estimators, are directly related to the quality of the learned heuristic function. Finally, we empirically detail which factors have the greatest impact on the quality of the learned heuristic function.
Biography: Dr. André G. Pereira is a professor at the Federal University of Rio Grande do Sul, Brazil. His research aims to develop and explain the behavior of intelligent systems for sequential decision-making problems. Dr. Pereira has authored several papers on top-tier venues such as IJCAI, AAAI, and ICAPS. These papers contribute towards explaining the behavior of heuristic search algorithms, how to use combinatorial optimization-based reasoning to solve planning tasks, and how to use machine learning techniques to produce heuristic functions. Dr. Pereira is a program committee member of IJCAI and AAAI. His doctoral dissertation was awarded second place in the national Doctoral Dissertation Contest on Computer Science (2017), and first place in the national Doctoral Dissertation Contest on Artificial Intelligence (2018). Dr. Pereira advised three awarded students on national events, including first place and finalist in the Scientific Initiation Work Contest (2018, 2022), and finalist in the Master Dissertation Contest on Artificial Intelligence (2020).
Alan Miller and The Virtual Open Worlds team appeared in The Herald earlier this month promoting their digital reconstruction of Fort William for the West Highland Museum
Using VR headsets, the team created a fully immersive virtual reality model of the old fort in Fort William in the days leading up to the Battle of Culloden on April 16, 1746.
This fully-funded position will aim to improve both the modelling capabilities and the solving performance when confronting Automated Planning problems. We seek motivated candidates with a strong background in Computer Science, with excellent programming skills and some previous knowledge and experience in solving combinatorial optimisation problems.

Proposal and Context
Software is large and complex. Ubiquitous systems, such as weather forecasting, medical imaging, advanced AI and big-data processing are extremely expensive and time-consuming for software companies to produce. Moreover, they often comprise many subtle bugs that can have disastrous consequences, are difficult to find, and difficult or impossible to fix. What developers need are specialised software refactoring tools that help them develop these important and complex systems in a safe and semi-automated way, reducing developer time, human error and overall increasing productivity, saving companies and customers money, and providing robust, safe, systems that have been developed in a responsible and trustworthy way.
Refactoring is the process of changing the structure of software without changing what it does: in effect, refactoring is about helping the programmer re-purpose their code to make it more understandable, accessible, or amenable to further change in the program’s design. It is often a process that developers use on a daily basis by manually changing code to reflect an API change, re-purposing methods, eliminating duplicated code, remaining variable parameters and function names, generalising functions, etc. However, this process is rather tedious and cumbersome to apply manually: effecting a structural change that could potentially affect millions of lines of code across thousands of files is inevitably error – prone.
The advent of refactoring tool-support provides developers with automated transformations that they can apply to their code base, usually through an existing IDE interface. Refactoring tools, on the other hand, provide a way to apply refactorings across an entire code base in a semi-automatic way: they rely on the user to make certain choices about which refactorings to perform but are automatic in their underlying machinery. This automated underlying machinery means that both simple and complex refactorings can be applied to large code bases comprising thousands of files and millions of lines of code instantly.
However, automated tools are prone to bugs. This has the potentially disastrous consequence of a refactoring tool refactoring a program into one that contains subtle bugs or changes in behaviour. Despite the obvious implication that this will refactor software to contain, perhaps, subtle and difficult-to-spot bugs, it also erodes developers’ confidence in using refactoring —and general software tools— in general. Furthermore, a refactoring that introduces errors or is not trustworthy requires the programmer to inspect the transformed code, therefore taking out the benefit of using an automated tool in the first place. The problem is also amplified in that refactoring tools are extremely cumbersome, laborious and difficult in themselves to implement, especially over large programming languages, such as Haskell. This makes the refactorings deployed in such tools limited, both in number and applicability.
What is needed is to answer the following research questions:
Exploratory Ideas
The PhD will be exploratory in nature. Here are some ideas for research directions to investigate as part of the PhD:
Supervisor and Background
The PhD project is to be supervised by Dr Christopher Brown, a lecturer in the school of computer science who has over 18 years of experience working in the field of refactoring, program transformation and functional programming. Dr Brown contributed to the original HaRe (Haskell Refactorer) system, developed at the university of Kent, and has since developed a number of new refactoring tools for a variety of languages, including Haskell, Erlang and C/C++ for introducing and tuning parallel programs. Dr Brown also works in the field of formal semantics, with prior work on formalising refactorings and using types to reason about e.g., extra functional properties of imperative systems for embedded languages.
The PhD project fits directly with the research vision of the supervisor, who is also working on building refactoring tools for dependently typed languages, such as Idris and Pi-Forall.
The Programming Languages Research Group
The Programming Languages Research Group has a long history in functional programming and type theory. This project would directly fit with the group’s general vision of:
