Jonathan Knappett

This 3.5-year D.Phil. studentship at the University of Oxford's Department of Engineering Science offers an exciting opportunity to research nature-based and biomimetic foundation systems in geotechnical engineering. The project, supervised by Professor Jonathan Knappett and Professor Chris Martin, investigates how tree root systems develop as natural 'foundations' in response to environmental loads, such as wind and slope, and how these biological strategies can inspire innovative, efficient engineering solutions. The research will begin by exploring the behaviour of various tree root architectures under vertical, horizontal, and moment loading using advanced numerical modelling and physical model testing. This phase aims to deepen understanding of root-soil interaction, with direct applications to hazard assessment for trees in extreme storms and the use of trees in nature-based solutions, such as tsunami protection by mangroves. Building on these findings, the project will develop and evaluate biomimetic foundation concepts that can be scaled and optimised for diverse engineering applications. Potential uses include railway electrification gantries, transmission tower and solar farm foundations, anchorage systems for floating offshore renewable energy, and low-rise building foundations in remote areas. These systems promise to minimise embodied carbon and installation requirements by leveraging efficient geotechnical performance and modular assembly. The studentship is fully funded through the Department of Engineering Science, covering course fees for home or overseas students and providing a tax-free stipend of approximately £20,780 per year for the first year, with at least this amount for the remaining duration. Applicants should hold a first class or strong upper second-class undergraduate degree in Engineering, Applied Mathematics, or Physics, and possess excellent English communication skills. Desirable skills include prior study in geotechnical or structural engineering, programming ability in Matlab or Python, and experience with finite element analysis. Applications are open to both home and overseas students. The deadline for applications is noon on 3 March 2026, with the programme commencing in October 2026. Interested candidates are encouraged to contact Professor Jonathan Knappett for informal enquiries and must submit a graduate application form via the University of Oxford website, quoting reference 25ENGCI_JKin.

[Full award: course fees covered for home or overseas students plus tax-free stipend of approximately £20,780 per annum for the first year, and at least this amount for a further two and a half years.] The University of Oxford is offering a fully funded 3.5-year D.Phil. (PhD) studentship in Geotechnical Engineering, focusing on nature-based and biomimetic foundation systems. This research project, supervised by Professor Jonathan Knappett and Professor Chris Martin, investigates how tree root systems provide natural 'foundations' that adapt to environmental loads, such as wind and soil movement. By understanding the architecture and geometry of root systems under various loading conditions, the project aims to develop innovative biomimetic foundation concepts that mimic these natural mechanisms, potentially reducing material usage and embodied carbon compared to conventional engineering solutions. The research will begin with an exploration of different tree root system architectures using advanced numerical modelling and physical model testing to simulate root-soil interactions. The findings will have direct applications in hazard assessment for trees exposed to extreme storms and in designing nature-based solutions for environmental protection, such as tsunami barriers formed by mangroves. The second phase will use these insights to design and evaluate scalable biomimetic foundation systems for diverse engineering applications, including railway electrification gantries, transmission tower and solar farm foundations, anchorage for floating offshore renewable energy systems, and low-rise building foundations in remote areas. This studentship is funded by the Department of Engineering Science and is open to both home and overseas students. The award covers full course fees and provides a tax-free maintenance stipend of approximately £20,780 per year for the first year, with at least this amount for the remaining duration. The project is ideal for candidates with a strong academic background in Engineering, Applied Mathematics, or Physics, and excellent English communication skills. Desirable skills include prior study in Geotechnical or Structural Engineering, programming experience in Matlab or Python, and familiarity with Finite Element Analysis. Applicants should submit a graduate application form via the University of Oxford website, quoting reference 25ENGCI_JK in all correspondence and their application. Informal enquiries are encouraged and can be directed to Professor Jonathan Knappett at [email protected]. The application deadline is noon on 3 March 2026, in line with the University's admissions schedule. The successful candidate will join a world-class research environment and contribute to cutting-edge developments in sustainable geotechnical engineering, with a start date in October 2026.

[Full award: fees plus stipend. Course fees are covered at the level set for home or overseas students, as applicable. Stipend is approximately £21,805 per year for the first year and at least this amount for a further two and a half years.] PhD/D.Phil. studentship in Geotechnical Engineering at the University of Oxford This 3.5-year D.Phil. studentship is based in the Department of Engineering Science at the University of Oxford and focuses on nature-based and biomimetic foundation systems . The project is supervised by Professor Jonathan Knappett and Professor Chris Martin . The research investigates how tree root systems act as natural foundations under combinations of vertical, horizontal, and moment loading. Using numerical modelling of complex root-soil interaction alongside physical model testing, the project aims to identify the controlling mechanisms that govern resistance and overturning stability. The work has direct relevance to windthrow hazard assessment , as well as broader applications such as mangrove protection against tsunamis. In a second phase, the project will use insights from tree root architecture to develop and evaluate biomimetic foundation concepts . These concepts may be scaled and optimised for applications including railway electrification gantries, transmission towers, solar farms, floating offshore renewable energy systems, and low-rise buildings in remote areas. The project is especially appealing to students interested in geotechnical engineering, structural mechanics, modelling, and sustainable infrastructure design, with a focus on reducing embodied carbon and material use. Funding : This studentship is fully funded through the Department of Engineering Science. It is open to both home and overseas students. Course fees are covered at the appropriate home or overseas rate, and the stipend is approximately £21,805 per year for the first year, with at least this amount for a further two and a half years. Eligibility and requirements : Applicants should hold a first-class or strong upper second-class undergraduate degree with honours, or equivalent, in Engineering, Applied Mathematics, or Physics. Prior study in Geotechnical Engineering, Structural Engineering, or a cognate area such as Continuum Mechanics or mechanical component/materials testing is expected. Strong written and spoken English is required, meeting the University’s higher-level entry requirements. Programming in Matlab or Python and experience with Finite Element Analysis are desirable. Application : Candidates must submit a graduate application form through the University’s application system and should quote reference 27ENGCI_JK .
