The Project

Mobile apps can be considered to be in a state of continuous beta release with minor and major releases being issued regularly. As always, changes bring the risk of (re)introducing errors to previously working code, necessitating regression testing to eliminate such unwelcome side effects. Testing user interfaces in particular can frequently be a manual and tedious process, which is at risk of human error due to inattention, missing particular paths, etc.

There are some promising approaches to automating some of this testing, and so this research would seek to investigate artificial intelligence and/or computer vision techniques that can address this problem. We already have one company interested in providing exemplar real-world apps and data sets to support this research. The student will have also access to the University’s new multi-million-pound DigiTech centre, based on the Adastral Park site, which boasts state-of-the-art machines and an AI Compute Server.

Candidate Requirements

Applicants should hold, or expect to receive, a First Class or good Upper Second Class Honours degree (or the equivalent). A master’s level qualification would also be advantageous but not essential.

Knowledge of, or a strong interest in mobile app development, software testing and artificial intelligence would be useful.

Non-UK applicants must meet our English language entry requirement.

The Project

The protection of personal data is becoming increasingly important, particularly with respect to the explosion of internet and cloud-based services that make use of personal data as part of a revenue generating business model. The use of (fully) homomorphic encryption techniques has been demonstrated in recent years to be privacy preserving for a growing number of applications, for example gene imputation. The techniques currently require in-depth expert knowledge of cryptography, but recent work (for example at Microsoft) has begun to investigate compiler technologies that would make privacy-preserving encryption accessible to software developers. This research would involve the development of advanced compiler models and software libraries that will then enable service developers to build privacy-preserving tools without needing to know anything about the personal data of an individual. It is expected that one or more cross-discipline case studies will be developed in particular application areas to demonstrate the usability and effectiveness of the research. The student will have access to the University’s new multi-million-pound DigiTech centre, based on the Adastral Park site, which boasts state-of-the-art machines and software dedicated to cyber security.

Candidate Requirements

The Project

The use of Open Source Intelligence (OSINT) to assist in the investigation of alleged crimes is a well-established approach, with organisations such as Bellingcat carrying out ground-breaking work in obtaining and analysing possible evidence from online sources. One of the essential criteria for assessing potential evidence is that of credibility – it is often a non-trivial task, even with dedicated tool support, to sift through large amounts of potentially relevant information to assess the veracity and relevance of one or more datasets. Techniques from artificial intelligence (specifically machine learning) offer promise here, and this research would aim to develop models and corresponding implementations which could help to speed up OSINT analysis and investigation. The student will have access to the University’s new multi-million-pound DigiTech centre, based on the Adastral Park site, which boasts state-of-the-art machines and software dedicated to cyber security.

The Project

Background and Motivation

Messenger RNA–or mRNA– is an essential component of all living organisms. mRNA is a messenger - it interacts with other components in cells, carrying instructions to make a specific protein. mRNA delivers these instructions, or “blueprints” so that cells can put the protein together. Once this process is complete done, an mRNA is broken down by the body.

mRNA teaches human bodies how to make their own medicine – COVID19 mRNA vaccines are only one of the examples where mRNA can be used to give cells directions to make a particular protein. Cardiovascular diseases are another area of application, where studying the proteins missing or produced by such groups of patients can help scientists produce a treatment plan or new medicines.

The structure of mRNA is still not fully mapped and still holds secrets for scientists, and this project explores the idea of using Machine Learning or more specifically, Deep Learning for Natural Language Processing to explore novel ways of extracting patterns and genes and protein information from mRNA sequencing data.

Project Aims

The aim of the project is to work with mRNA sequencing data from cardiovascular disease patients employing methods widely used in detecting patterns in text data from the machine learning and deep learning to study the structure of mRNA and detect its minimal units from existing sequencing data.

The applicant will initially be working on public datasets available in the machine learning and bioinformatics community and inhouse sequencing datasets held by the Suffolk AI (Artificial Intelligence) Research Group members. Machine and Deep learning models will be developed by the student to take multi-modal data as input and generate the high-quality representations as mentioned above. At a later stage, a new dataset would be constructed, and novel algorithms will be developed upon that to answer the challenging questions within this topic and beyond.

Facilities

PhD researchers affiliated with this project will be based in our state-of-the-art DigiTech Centre at Adastral Park, launched in the summer of 2021. A collaboration between the University of Suffolk and BT, with funding from the New Anglia Local Enterprise Partnership (LEP), the centre has been established to provide training in innovative digital skills for people looking to pursue careers in the nationally essential information and communications technology (ICT) sector, as well as fuelling high tech businesses who increasingly require access to a talented technology workforce.

The centre houses four high-end computer laboratories complete with industry-standard software and tools and a dedicated high-end AI server. In addition, PhD students will have access to dedicated comping labs at the Atrium building, in Ipswich, technology focused communal areas, full access to the library resources and other on campus facilities.

Candidate Requirements

Applicants should hold, or expect to receive, a First Class or good Upper Second Class Honours and/or a postgraduate degree with Distinction (or an international equivalent). We also consider applicants from diverse backgrounds that have provided them with equally rich relevant experience and knowledge. Full-time and part-time study modes are available.

Applicants should have the following essential knowledge and skills:

• Strong programming skills (Python, C, Java, etc.)

The Project

Background and Motivation

The Industry 4.0 concept aims to the deployment of a large amount of sensor and actuator devices forming an Industrial Internet of Things (IIoT) network. Such IIoT information systems can collect data from all over the shop floor or agricultural unit and can be aggregated to the edge of the network. Edge computing, Edge Intelligence and Federated Machine Learning have been playing an important role in that ecosystem, which heavily rely on the integration of diverse technological solutions to build an intelligent manufacturing ecosystem through the amalgamation of customization, predictive maintenance, digital twin, web-based systems, open connectivity, etc. Edge intelligence, i.e., artificial intelligence (AI) applications with edge computing (edge AI) for training/testing or inference, is an important element for IIoT applications to build a model that can learn from the high amount of aggregated data.

Predictive maintenance is a method of preventing future machinery failure by analysing data during production to detect abnormalities ahead of time, so appropriate measures can be taken before damage can be done to the production line. With faults and failures forecast well before their occurrence, saving money and time for businesses and manufacturing companies, implementing predictive maintenance programs in manufacturing sectors requires condition monitoring of equipment's critical variables and then deploying intelligent techniques to predict the occurrence of failure. The data processing and predictions in predictive maintenance can be ventured as Edge AI techniques, which will be more feasible options for small- and medium-scale industries.

Project Aims

The applicant will work with the supervisor and other academic staff within the Digital Futures and Suffolk AI Research Group to define their specialised area of work depending on their expertise, speaking to one of the areas above. The School and the Digital Futures Institute has excellent links with industry, and it is expected that the project will benefit from direct input and collaborations with local manufacturing partners and cross-pollination of ideas (EDF Sizewell, Openreach BT, Celotex among others).

The Project

Previous research into shared participation in recreational experiences has shown to positively contribute to factors such as wellbeing and experience enjoyment (Boothby, et al., 2014; Boothby, et al., 2016). Additionally, there have been recent exploratory studies aimed at better understanding player perspectives with regards to shared recreation (Haqq & McCrickard, 2020). What is not currently clear, are the underlying mechanisms that contribute to a gameplay experience that is not only enjoyable, but also promotes socially meaningful interactions and other factors such as connectedness with nature.

The goal of this project, is to make contributions to the exergame and interdependent play space for the purpose of improving a person’s physical and mental wellbeing. It is expected that the PhD student will engage in a body of research aimed at understanding and establishing mechanisms that contribute to this area of game design and also design and build such games that can be played by the general public. Typical outcomes will involve submitting theoretical and practical work to annual conferences such as Foundations of Digital Games and CHI PLAY. At the University of Suffolk, you will have access to our state-of-the-art games lab, the specialist laboratories in our DigiTech Centre, as well as other relevant facilities such as our Sports Science lab.

Candidate Requirements

Applicants should hold, or expect to receive, a First Class or good Upper Second Class Honours degree (or the equivalent). A master’s level qualification would also be advantageous but not essential.

Knowledge of games development and/or programming is essential. It is advantageous to have a working knowledge of univariate statistics but this is not essential and can be learned throughout the PhD.

Non-UK applicants must meet our English language entry requirement.
