PhD in Optimizing Canopy Photosynthesis in Controlled Environment Agriculture Wageningen University & Research in Netherlands

Are you curious about how photosynthesis performs in the real world, over hours, days, and weeks, and how can we use that knowledge to improve greenhouse production? As a PhD candidate, you will investigate how photosynthesis operates over different temporal and spatial scales in crops growing under realistic greenhouse and vertical farming conditions. By combining continuous monitoring (e.g. chlorophyll fluorescence imaging) with microclimate measurements, you will uncover photosynthetic limitations and regulatory processes (e.g. acclimation) that are often overlooked due to their long temporal dynamics. The aim is to interpret these dynamics in a physiological framework and translate them into actionable insights for climate control and crop performance.

You will work with chlorophyll fluorescence imagers, leaf-level validation sensors, and modelling tools to support interpretation of canopy-scale photosynthesis. This project is part of the GreenControl programme, funded by the Dutch Research Council (NWO) and 11 companies. The programme encompasses 7 PhD students appointed at the universities of Wageningen, Delft, Eindhoven, and Twente. Within GreenControl, you will collaborate with another PhD in the same group focusing on water-related traits and colleagues across different disciplines, technology companies, and growers, ensuring that your research results are directly usable in operational climate‑control strategies.

Your duties and responsibilities include designing and executing greenhouse and vertical‑farm experiments using chlorophyll fluorescence imaging and supporting sensors to infer canopy photosynthesis, investigating short‑ and long‑term regulatory processes, and identifying limiting factors in canopy photosynthesis under realistic environmental fluctuations. You will use and validate existing multilayer photosynthesis models that integrate microclimate gradients to support the interpretation of canopy photosynthesis dynamics across time scales. Collaboration with technology providers, growers, and researchers is key to translating physiological insights into improved climate-control strategies for greenhouse production.

The research is embedded within the chair Horticulture and Product Physiology, and you will be a member of the team of Silvere Vialet-Chabrand, led by Prof. Leo Marcelis. The Horticulture and Product Physiology (HPP) group at Wageningen University & Research focuses on understanding and controlling plant growth, development, and product quality, particularly in controlled environments such as greenhouses and vertical farms. By integrating plant physiology, modelling, and data-driven approaches, the group aims to predict plant performance and optimize production systems across the entire supply chain, contributing to sustainable and efficient horticulture.

Funding is provided by the Dutch Research Council (NWO) and 11 companies as part of the GreenControl programme. Applicants should have a strong background in plant physiology, biology, or a related field. Experience with experimental design, data analysis, and modelling tools is desirable. Skills in greenhouse or vertical farming research, chlorophyll fluorescence imaging, and microclimate measurements are advantageous. Proficiency in English is required. Specific degree level and GPA requirements are not mentioned.
