PhD studentship in sustainable energy at Imperial College London through the Department of Civil and Environmental Engineering and the Grantham Institute - Climate Change and the Environment. This funded opportunity is aimed at candidates with a degree in an Engineering or Science discipline who want to pursue research in sustainable energy , energy systems , low-carbon technologies , energy economics and policy , energy transmission and storage , sustainable transport , synthetic fuels , urban energy systems , and related data-driven approaches. Funding : 3.5 years of support, including an annual stipend of £23,805, home tuition fees covered up to £5,238 per year (UKRI home fee level), and £5,000 for allowable research expenses. The post is open to both home and international students, but international applicants must arrange additional funding for the tuition fee difference. How it works : applicants should first identify an academic supervisor in the department and email them a cover letter and CV. A full PhD application is not required at this initial stage. Deadline : final date to approach a supervisor is 25 May 2026. Interested candidates are encouraged to contact supervisors as early as possible. Institution : Imperial College London.

This fully funded PhD studentship at Imperial College London offers an exciting opportunity to join the Water Systems Integration Group in the Department of Civil and Environmental Engineering. The project, supervised by Professor Ana Mijic and co-supervised by Dr Jimmy O’Keeffe (Dublin City University), is part of an international research consortium focused on enabling local knowledge production for water security. Collaborations extend to Dr Rossella Arcucci (Imperial College London), Dr Barnaby Dobson (Trinity College Dublin), and Dr Seifu Tilahun (International Water Management Institute). The research addresses the complexity and dynamism of agricultural systems, which integrate biophysical processes such as soil, water, and crops with human decision-making and institutional frameworks. These systems are vital for human livelihoods but also pose significant environmental challenges, particularly regarding water use and agrochemical runoff. The project aims to develop advanced integrated computational models that capture key interactions across multiple spatial and temporal scales, providing new insights into agriculture's role within the broader human–water cycle. This interdisciplinary PhD will focus on improving the representation of agricultural systems within flexible integrated water system models. Unlike traditional detailed modelling approaches, the project will create a reduced complexity representation of agricultural systems, embedded within integrated water system models and enhanced through machine learning (ML) enabled data assimilation. The research will test these simulations for consistency of agricultural impacts and policy relevance in diverse settings, leveraging a global network of collaborators. You will work with WSIMOD, a state-of-the-art integrated water system model, extending it by developing a globally generalisable agricultural systems module capable of representing key global crops such as wheat, rice, maize, soybean, and potato. The project will explore hybrid WSIMOD–ML approaches, using ML-based data assimilation techniques to support model parameterisation, evaluation, and uncertainty reduction. The PhD is embedded in a larger international consortium project for global water assessment, with the results supporting evidence-based decision-making on water security and agricultural productivity. The ideal candidate will have a strong interest in machine learning and data assimilation approaches, experience in agricultural systems modelling, and quantitative data analysis. Applicants should hold a First Class Degree (or international equivalent) in water engineering, environmental engineering, or a closely related discipline with a strong quantitative or data-analysis component, as well as a Masters level degree qualification. Experience with modelling and programming, ideally using Python, for water systems analysis is required. Enthusiasm for collaborative and interdisciplinary research, along with excellent English communication skills, is essential. The studentship provides funding for 4 years from the start date (1 October 2026), covering international tuition fees and a tax-free stipend at the standard UKRI London rate. Applications are accepted year-round and will be reviewed until the position is filled. To apply, contact Professor Ana Mijic ([email protected]) for further details and informal discussions. Submit your current CV, a covering letter (maximum 1 page), and contact details of two academic referees by email, using the subject line 'PhD Application: Hybrid Machine Learning–Integrated Modelling of Global Agricultural Systems'. Application via the Imperial College Registry is not required at this stage.

Imperial College London's Water Systems Integration (WSI) Group, led by Professor Ana Mijic, is seeking highly motivated PhD candidates for projects in integrated water system modelling. The group has developed the WSIMOD framework, which enables flexible modelling of the terrestrial water cycle, including urban and rural interactions, natural processes, infrastructure, and human factors. Three PhD projects are available, each advancing key aspects of WSIMOD's development: P1: Modelling the whole-water cycle at a global scale using open-source datasets, focusing on water-system modelling, Python programming, and data assimilation. P2: Uncertainty assessment of integrated water system models, emphasizing uncertainty quantification, validation, and statistical analysis. P3: Development of LLM-based agents for hybrid water system modelling, combining machine learning, Python, and scenario analysis. Applicants must be UK Home students or of Chinese nationality, with a strong academic record (first-class degree or distinction), interest in water cycle modelling and management, and good programming skills (ideally Python). Relevant professional or research experience is valued. Candidates will apply for departmental PhD funding, with deadlines in January and March 2026. Funding details are not specified, but the positions are for funded PhD opportunities. To apply, email Professor Ana Mijic with your CV and a motivation paragraph for your chosen project. Internal interviews will be held until a suitable candidate is identified. Key research areas include integrated water system modelling, uncertainty quantification, machine learning, and the application of LLM agents in environmental science. The WSI Group offers a collaborative environment at Imperial College London, a leading institution in environmental and civil engineering research.
