A three-year PhD position funded by the Austrian Science Fund (FWF) will become available at the Institute of Botany, University of Natural Resources and Applied Life Sciences (Universität für Bodenkultur) Vienna, Austria. Tentative start date of the project is October 2017.
Leaves have an intricate structure that is well-known to affect their ability to perform photosynthesis. It remains difficult to describe quantitatively how anatomical features, such as cell shape, chloroplast positions, etc. affect the photosynthetic process . Although three-dimensional reaction diffusion models of the leaf anatomy have been developed, they have not often been parametrized by accurate measurements of anatomy and physiology.
Recent work has shown that leaf anatomy can change rapidly under drought stress, and this provides an interesting opportunity to examine the effect of anatomy on leaf photosynthesis in detail. To this end, high-resolution three-dimensional images are obtained for poplar leaves exposed to water deficits. At the same time, the photosynthetic performance of the leaves will be characterized by gas-exchange measurements. The anatomy observed during these experiments will be analysed using state-of-the-art reaction diffusion models of the leaf. Apart from visits to collaborators (France, Canada and/or Japan), work will be based in Vienna.
The ideal candidate has experience electron and/or light microscopy, sample preparation (including microtome), gas-exchange, leaf hydraulic measurements and good English writing skills. Courses in various ecophysiological techniques relevant to the project will also be offered during the studies.
Formal applications including a curriculum vitae, a letter explaining why you are interested in this research and two letters of support should be received before July 15.
