23 Postdoctoral Fellowship at University of Hamburg, Germany

The applicant will work on designing ocean observing for measuring the large-scale ocean circulation. This work will have two main components, with the relative distribution of work focus to be discussed with the successful candidate. One component will be testing and using novel in situ pressure sensors which are designed to correct for drift. These sensors offer the potential to reconcile inconsistencies between existing AMOC observing arrays (e.g., Frajka-Williams et al. 2018, Danabasoglu et al. 2021). The successful candidate will use data records from these new sensors (currently deployed and to be deployed in Sept 2023) to evaluate the extent to which they are able to self-correct drift. This work will use of a wide range of auxiliary datasets (altimetry, gravimetry, Argo profiling floats and tall moorings), and be carried out in collaboration with both physical oceanographers and geophysicists. A second component will be in using machine learning techniques to re-evaluate what an optimal AMOC observing system might comprise. This approach is complementary to alternate approaches (e.g., observing system experiments and adjoint methods), but instead asks a more general question of what information can be gained from particular observation types and distributions.

The PyMiCCs project is a collaborative research program at Universität Hamburg, Geisenheim University, ithaka institute and PIK Potsdam, funded by the German Federal Ministry of Education and Research (BMBF).The Project aims to investigate the potential of enhanced weathering in combination with biochar application (PyMiCCs products) for the incorporation and stabilization of carbon in arable soils, and to evaluate the consequent potential as a carbon capture and storage technology for climate-change mitigation. To achieve this goal, the project combines laboratory, green house and field experiments with process-based numerical modelling and agro economic potential analyses.

The Biological Psychology and Neuropsychology (BPN) unit of the University of Hamburg (Germany) seeks a PhD candidate with a background and a research interest in multisensory processing and neuroplasticity using experimental research combined with either EEG, fMRI or computational modeling techniques.The position is funded by the University of Hamburg (E13, 65%, §28(1)) and comes with a teaching requirement in Biopsychology and Experimental Psychology of 2,6 h/week (LVS). The PhD project will address multisensory processing and neuroplasticity.

The position will be filled to work on a PhD research project on membraneless compartments in plant cells that form upon abiotic stress or in plant immunity. Such compartments may contain RNAs and proteins with intrinsic properties (such as prion-like domains) that make them prone to form condensates in a process called liquid liquid phase separation (LLPS). The focus will be on proteins, whose localisation to condensates under certain stress conditions has already been established. By combining methods from biochemistry and molecular genetics with cell-biological techniques such as confocal live cell imaging microscopy and electron microscopy the structure, function, biomolecular interactions and dynamics of these proteins in the context of LLPS will be studied in plant cells. The goal of this project is to uncover novel aspects on formation, dissolution and function of condensates for plant performance and stress response.

The research group of Petra Berenbrink at Universität Hamburg is among the leading research groups in Germany in the areas of theory of distributed and parallel computing. The research group acquired several research projects in cooperation with several national and international researchers.Our research group is now looking for postdoctoral researchers or a PhD student to work opinion distributed processes. Addition to research work, postdocs participate in the supervision of students but there are no teaching duties. The contracts include occupational health benefits. The starting dates are negotiable and there is an option to renew the contract by another 2-3 years if the project is extended.

The goal of the successful candidate is to design signal processing and machine learning algorithms to analyze and evaluate existing tools for processing social signals in face-to-face (F2F) situations for their performance in immersive virtual group meetings. This project is part of the interdisciplinary research group “Computational Human Dynamics – Multimodal Social Signal Processing of Dyadic and Group Interactions”, which integrates fundamental science, innovative methods, and applications in psychology and computer science. This Cross-Disciplinary Lab (CDL) is funded by the central funds of the University of Excellence and is running in the House of Computing and Data Science (HCDS). All involved researchers will actively contribute to the group, e.g. via research colloquia, presentations, and interactive workshops.

The researcher will investigate the importance of ABCB transporters for adaptation to host plant-derived cardenolides in the large milkweed bug, a species that recycles the toxins for its own anti-predator defense. The project analyses the effect of RNA interference mediated knockdown of specific ABCB transporters on uptake and trafficking of cardenolides and will screen for phenotypic effects on the bugs. To investigate the substrate specificity of the transporters and disentagle the transport network through the body, relevant cardenolides will be isolated from bugs or host plants by LC-MS techniques and fed or injected to the bugs.

We seek candidates for a PostDoc positions in the Excellence Cluster ‘Climate, Climatic Change, and Society’ (CLICCS, https://www.cliccs.uni-hamburg.de/) funded by the German Research Foundation. The position is part of the project ‘Carbon Dynamics in the Arctic’ (CLICCS A1) aiming to quantify Arctic sinks and sources of carbon and nutrients in a changing climate. The project considers a multitude of approaches and scales including laboratory experiments, field observations and pedon-scale to global-scale model simulations. The open position will be part of the working group “Dynamics of Soil Processes” at the Institute of Soil Science.The research associate will study the impact of nutrient availability, particularly nitrogen, on plant productivity and carbon fluxes in permafrost-affected soils. Of particular interest is the link between nutrient fluxes (e.g. from N2-fixation) and carbon fluxes in the soil-plant-atmosphere continuum. This research will be based on a combination of Arctic field studies and controlled laboratory experiments and analysis. Element fluxes between soil, vegetation and atmosphere as well as the impact of microbial processes will be quantified under natural and highly controlled laboratory conditions using stable isotope techniques, incubations of soil mesocosms under a controlled climate, soil chemical and physical analysis and greenhouse gas flux measurements in the field and the laboratory. The fieldwork will be conducted in close cooperation with further researchers in the project.
