PhD position – modelling effects of spectral variation on photosynthetic light use efficiency in canopies

Your job

Photosynthesis is one of the most fundamental biological processes on Earth, using sunlight to produce sugars and ultimately, the food we eat. Although the modelling of photosynthesis has received much attention, most models currently include light harvesting in a simplified manner. For example, they do not include the effect of changes in light colour and intensity that leaves experience throughout a canopy on timescales ranging from sub-seconds to seasons. The question is: how do these changes affect photosynthetic light use efficiency?

As a PhD candidate, you will contribute to answering this question and build on and improve current photosynthetic models. This is achieved using a combination of modelling and experimentation to incorporate the local light-spectrum that the chloroplast receives, considering how it is absorbed by the photosystems and how this energy is subsequently used to drive the fixation of CO2 into sugars. The model will be parametrized and experimentally validated by measuring the rates of electron transport, CO2 assimilation, and oxygen exchange at a range of timescales.

Your qualities

You are a person that likes to understand and unravel complex systems, with a fascination for photosynthesis and with experience in modelling and experimentation, preferably including techniques related to photosynthetic gas-exchange and spectroscopy.
You also:

• Have an MSc degree in plant sciences, biology, life sciences or equivalent
• Have a solid background in mathematics and modelling, applied to biological processes, such as photosynthesis
• Have experience with experimental techniques and analysis related to photosynthesis, as well as their analysis
• Have excellent command of the English language, both in writing and conversation.
• Enjoy working independently, but also embrace opportunities to collaborate, to discuss and interact with others within and outside your field or research.

For this position your command of the English language is expected to be at C1 

level

. Sometimes it is necessary to submit an internationally recognised Certificate of Proficiency in the English Language. More information can be found

Collective Labour Agreements for Dutch Universities (CAO-NU)

(scale P). This is based on a full-time working week of 38 hours. We offer a temporary contract for 18 months which will be extended for the duration of the project if you perform well (48 months).

There are plenty of options for personal initiative in a learning environment, and we provide excellent training opportunities. We are offering a unique position in an international environment with a pleasant and open working atmosphere.

You are going to work at the greenest and most innovative campus in Holland, and at a university that has been chosen as the “ Best University ” in the Netherlands for the 18th consecutive time.

Coming from abroad
Wageningen University & Research is the university and research centre for life sciences. The themes we deal with are relevant to everyone around the world and Wageningen, therefore, has a large international community and a lot to offer to international employees.
Our team of advisors on Dutch immigration procedures will help you with the visa application procedures for yourself and, if applicable, for your family.

Feeling welcome also has everything to do with being well informed. Wageningen University & Research’s International Community page contains practical information about what we can do to support international employees and students coming to Wageningen. Furthermore, we can assist you with any additional advice and information about helping your partner to find a job, housing, schooling. For instance under the “30% rule”, certain categories of international staff can receive tax exemption on approximately 30% of their gross salary.
