PhD Position at the Helmholtz Centre for Environmental Research - UFZ, Leipzig, Germany

The Department Computational Hydrosystems is offering a PhD position to work on the interface between soil, hydrology, vegetation and the atmosphere within the context of the newly funded DFG Project "Disentangling seasonal vegetation effects on ecosystem evapotranspiration and water use efficiency of a Mediterranean savannah-type oak forest."

A functional understanding of evapotranspiration and photosynthesis is required to understand the development of water and carbon fluxes, particularly in water-limited ecosystems where global climate change is expected to intensify drought and alter precipitation patterns. The aim of this project is a detailed mechanistic evaluation of the water balance and water use efficiency of one typical Mediterranean savannah-type oak woodland, focussing on seasonal dynamics of over- and understorey vegetation.

The candidate will adapt a soil-vegetation-atmosphere transfer (SVAT) model to savannah-type ecosystems. This includes such diverse and challenging subjects as radiative transfer in heterogeneous landscapes, root water uptake of plant communities and hydraulic redistribution of roots including mycorrhizae. Primary focus of the thesis will be process descriptions in the SVAT model, but the candidate is also supposed to spend three to five months per year in Portugal helping with fieldwork.

We seek a highly motivated creative person with strong mathematical background, interest in interdisciplinary research and capability to work with a larger research group. Candidates should have a master (Diplom or equivalent) in the area of the mathematical-natural sciences. Candidates should have very good programming skills and a good knowledge of English. Plant physiology and isotope knowledge is a plus. We provide excellent supervision in a young dynamic team.

The place of work is Leipzig, Germany. Salary will be according to the appropriate civil service level TVÖD (E 13/2). Physically handicapped persons will be favored if they are equally qualified. Women are explicitly encouraged to apply to increase their share in science and research.
