Within the interdisciplinary Helmholtz project “Reduced Complexity Models – explore advanced data science techniques to create models of reduced complexity“ several Helmholtz centers aim at addressing and developing the following three components simultaneously and in a unified manner: uncertainty quantification, development of fast surrogate models and the identification of key parameters and dependencies.
The UFZ is therefore seeking for a Postdoc (m/f) for the subject: Development of surrogate hydrologic models with reduced complexity.

Within the DFG funded priority programme (PP) „Rhizosphere spatiotemporal organisation – a key to rhizosphere functions“ we are seeking for a motivated scientist (m/f) for supporting the speaker of the PP in all issues related to coordination. The overarching goal of the PP is to identify spatiotemporal patterns of biological, chemical and physical parameters in the rhizosphere; the mechanisms responsible for their development and their relevance for plant resource acquisition, plant health, soil carbon sequestration and soil structure development (http://www.ufz.de/spp-rhizosphere/).

PostDoc (molecular ecology or electroorganic chemistry) for developing Electrobiorefineries, 100% position for initially 3 years

Within the framework of a DFG-funded Forschergruppe, the UFZ offers one PhD position.

This PhD topic aims at the development and testing of new methods to eliminate organic pollutants from aqueous matrices such as contaminated ground- or wastewaters. The core idea consists in the generation of temporary steep temperature gradients in the close vicinity of metallic micro-wires. This enables one to activate high temperature processes - physical and chemical ones - in a solid adsorber or catalyst while the aqueous bulk phase to be treated remains largely at ambient temperature. The processes under investigation range from adsorption-desorption swing regimes up to hydrolysis and catalytic reduction or oxidation of chemicals. Kinetics and mechanisms of the underlieing processes and chemical reactions will be studied.

Within the DFG funded priority programme (PP) „Rhizosphere spatiotemporal organisation – a key to rhizosphere functions“ (http://www.ufz.de/spp-rhizosphere/) we are seeking for two motivated PhD students (m/f). This sub-project aims at exploring the relevance of root growth and related soil structure formation for spatiotemporal patterns of chemical and biological properties and emergent system functions. The project covers a broad mix of methods ranging from soil physics and plant nutrition to 3D imaging and image processing in order to study plant-soil interactions in laboratory and field experiments.

A reliable assessment of the flooding hazard of river basins is crucial for many
disciplines ranging from water resources management to urban planning and
the insurance industry. However, the stochastic character of streamflows
makes this a difficult task, particularly when long series of observed discharge
data are not available. New methods promise to increase the reliability of the
estimates of flood magnitude and frequency, especially in conditions of data
scarcity, by exploiting a new conceptualization of hydrological processes.
This thesis work aims at identifying key climatic and landscape controls
on flooding potential of river basins, in order to develop a tool to assess
if available data series are long enough to provide reliable estimates of the
underlying hazard.
