Welcome to the Plant Biology Institute

The Plant Biology Institute, headed by Professor Steve Kelly, is a key part of the Ellison Institute of Technology (EIT) Oxford. The institute aims to develop impactful and commercially sustainable solutions for improving global food production and planetary health through pioneering plant science research.

The Plant Biology Institute will unite world‑class researchers who are focused on expanding the frontiers of plant science. Our research is focused on enhancing our ability to feed the planet while simultaneously improving the climate and ecosystem outcomes of food production. By embedding cutting‑edge plant science research within an organisation that is focused on solving global challenges at scale, we aim to accelerate the timeline from discovery to global impact.

Areas of exploration

Researchers will have access to state‑of‑the‑art laboratory and plant growth facilities and have opportunities to collaborate with experts at the forefront of research on AI, automation, and generative biology across the EIT ecosystem. They will also work with global leaders in market development, commercialisation, and impact creation. The Plant Biology Institute has long‑term substantial funding to support the unique scale and ambition of its vision.

Your Role

The Ellison Institute of Technology (EIT) is seeking a highly motivated and skilled Postdoctoral Researcher in Plant Molecular Biology to join its pioneering Plant Biology Institute to contribute to the ‘Biological Nitrogen Fixation’ program. This initiative seeks to engineer biological nitrogen fixation into widely grown crop plants to improve yields and reduce global reliance on synthetic fertilisers. The ultimate goal of this work will be to deliver transformative environmental, economic, and public health benefits by helping to support the transition to scalable and regenerative agricultural systems.

Your Responsibilities

The Postdoctoral Researcher will play a key role in designing and conducting experiments aligned with stage‑gated milestones in our plant engineering program. The main responsibilities of the successful candidate will be to optimise the expression, subcellular targeting, and sub‑assembly and higher‑order‑assembly of complex enzymatic systems in plant cells using transient and stable plant transformation approaches. Successful delivery of these research objectives will require expertise in advanced microscopy techniques and imaging, plant histology, and a strong foundation in molecular biology and plant genetic engineering. Insights generated from this work will directly inform and accelerate our synthetic biology strategy to enable the introduction of novel metabolic capabilities into high‑performance crop varieties.

The ideal candidate will have expertise in molecular biology and advanced microscopy techniques applied to plant tissues. This role offers a unique opportunity to conduct high‑impact research at the forefront of plant science while collaborating across multidisciplinary teams to drive innovation from lab to global impact.

The postdoctoral researcher will be expected to contribute to publications and IP generation and play an active role in translating research into real‑world and commercial solutions aligned with EIT’s mission of humane technological advancement. This is an exciting opportunity to develop as a scientific leader in a dynamic, well‑supported, and purpose‑driven environment.
