[Full tuition fees and annual tax-free stipend of £22,780 for Home, EU and International students.] This PhD studentship at Imperial College London offers a unique opportunity to investigate the complex interactions between offshore wind farms and cloud formation, with a focus on maximising wind farm performance using scientific machine learning. The project addresses how the operation of large offshore wind farms modifies the Marine Boundary Layer (MBL), influencing the formation of marine stratocumulus clouds and, in turn, affecting local mesoclimate and wind farm power generation. The research will use high-fidelity large eddy simulation (LES) codes and scientific machine learning tools, including real-time optimisers and actuator disc/line wind-turbine models, to simulate wind farms under various atmospheric conditions. The student will develop strategies for discovering self-similarity laws, quantised local reduced order models, and real data assimilation, gaining deep insight into the flow physics of cloud formation and wind energy. The successful candidate will be jointly embedded in the research groups of Prof. Oliver Buxton (expert in turbulence, wind-energy flows, and cloud microphysics) and Prof. Luca Magri (expert in scientific machine learning for aeronautical applications). Both groups host ERC projects, providing a vibrant and collaborative research environment. The studentship is fully funded for 3.5 years, covering tuition fees and providing a generous annual tax-free stipend of £22,780 for Home, EU, and International students. There is potential for international collaboration, including short research visits to The Netherlands. Eligibility requires a First class honours MEng/MSci or higher degree (or international equivalent) in Aeronautical/Mechanical Engineering or a closely related STEM field. Applicants should demonstrate strong academic performance and a willingness to learn new skills and techniques. The application process involves submitting a CV, transcripts, and a motivation statement for supervisor review, followed by a formal application for long-listed candidates. The deadline for applications is 8 January 2026.
