22 Postdoctoral Fellowship at University of Hamburg, Germany

Research associates will be expected primarily to teach and conduct research. The research associate will also have the opportunity to pursue further academic qualifications, in particular a doctoral dissertation. At least one-third of set working hours will be made available for the research associate’s own academic work.

The research associate can take part in the doctoral training program “collective decision making” and needs to acquire skills in quantitative empirical data analysis (if necessary) to write a doctoral dissertation in political science or political economy on a topic related to the research interests at the chair of comparative political science, particularly gender and politics, climate politics or sustainable fiscal politics, electoral competition, gender and representation.

The research associate will investigate small-scale physical dynamics at the air-water interface and physics of wind-wave interactions, as part of the research group “Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer (BASS)” funded by the German Research Foundation. The overall goal of BASS is to investigate the importance of the sea-surface microlayer (SML) as a biogeo- and photochemical reactor, and how its reactivity affects ocean-atmosphere interactions. Eight subprojects are collaborating in joint laboratory and field campaigns, among which are dedicated experiments at Universität Hamburg’s wind-wave tank. BASS combines interdisciplinary expertise, advanced technologies for millimeter-scale observations, core infrastructures for controlled experiments, and state-of-the-art analytical facilities at the molecular levels.

The Technology Platform Light Microscopy (TPLM) of Universität Hamburg (https://www.uni-hamburg.de/en/technologieplattformen/technologien/lichtmikroskopie.html) consists of several light microscopy facilities, including the newly established Department of Biology Light Microscopy Facility (BLMF). The BLMF operates 10 high-end microscopes, such as programmable widefield microscopes, point scanning confocal microscopes equipped for fluorescence lifetime imaging microscopy (FLIM), and spinning disc confocal microscopes.

We are looking for a motivated microscopy specialist who will be part of the TPLM team and in charge of the BLMF.

The successful candidate will work closely with and support researchers using the BLMF, helping them to design, perform and analyse light microscopy-based experiments. The recruited candidate will be involved in projects to develop novel tools, workflows, and methods for light microscopy. In addition, the successful candidate will be encouraged to design and carry out research projects that will lead to the development of novel microscopy methods and enable research groups using the BLMF to address their research questions.

In the period from as soon as possible until 31.12.2025, research associates will be expected primarily to teach and conduct research. The research associate will also have the opportunity to pursue further academic qualifications, in particular a doctoral dissertation. At least one-third of set working hours will be made available for the research associate’s own academic work.

In the period from 01.01.2026 for the remaining time duties include academic services in the project named above. Research associates may also pursue independent research and further academic qualifications.

The applicant is expected to perform quantum optics experiments using integrated photonics. This will involve the development of nanofabrication processes, non-linear optics, and integration of nanofabricated devices into a cryogenic measurement setup. Analysis of the acquired data and independent development of experimental protocols are expected. Another specific duty is teaching of three hours per week during teaching times (3 LVS) in the period from as soon as possible until 31.12.2025. Typical teaching duties are supervision of student labs or exercises.

We are looking for a highly motivated postdoc for our “Marine Geophysics” group at Universität Hamburg. The aim of the project is to investigate the interaction between tectonic and underwater volcanism in the Vesturdjúp Basin between Iceland and Greenland, as well as the eruption processes. Multi-channel seismic and hydroacoustic data are available for this purpose and will have been measured by the time the project starts. The project is a cooperation between the Universität Hamburg, the Helmholtz Center for Ocean Research Kiel GEOMAR, the University of Gdansk, the King Abdullah University of Science and Technology (KAUST), and the University of Reykjavik.

The overall mission of the project is to develop and validate non- or minimal invasive fish monitoring strategies for the assessment of fish communities in the German nature reserve “Sylt outer reef”. We will study fish communities and habitat utilization by state of the art underwater imaging, environmental DNA approaches and tagging studies. The project will be funded by the Federal Agency for Nature Conservation.

Intense coherent X-ray beams, combined with novel X-ray optics of high numerical aperture, open up new opportunities for ab initio phasing of macromolecular crystals and nanoparticles to recover information about their dynamics. This project aims to develop strategies, methods, and algorithms for time-resolved convergent-beam crystallography and Bragg ptychography using synchrotron radiation and X-ray free-electron laser pulses.

Duties include teaching and research in the respective department or institute. Research associates may also pursue independent research and further academic qualifications as well as acquire teaching experience. These duties are intended to promote academic achievement. Therefore, at least one-third of set working hours will be made available for the associate’s own academic work.

The increasing release of antibiotics, biocides, toxins, plasticizers and microplastics has a direct and indirect impact on microbial diversity and, through selection, promotes the spread of bacterial resistance mechanisms causing a high risk for human and animal health. In addition, climate change and other man-made factors increase and speed up these effects. The MOMOBIO-2 project will develop very detailed mainly omic-based data sets and models to track, monitor and predict the urban microbiota and changes in its biodiversity and resistance profile along the wastewater streams of the City of Hamburg as well as urban water bodies. Our main goal is to use changes in microbial biodiversity as an indirect measure for animal and human health.

The five-year project “BioValCat” (Enhanced Biomass Valorisation by Engineering of Polyoxometalate Catalysts), funded by the ERC Consolitator Grant 2022, aims to enable 100% carbon efficiency from complex biomass by developing innovative POM catalyst-solvent systems for aerobic and anaerobic applications and to develop this into an innovative and widely applicable process technology.

Polyoxometalates (POMs), as a unique class of anionic polynuclear metal-oxo clusters with high structural diversity at the atomic level, are highly promising candidates for the selective oxidation of biomass to organic acids. In the field of homogeneously catalysed, selective biomass conversion, POMs are already used intensively. One example for the potential of POMs is the already commercialised OxFA process, in which biomass is oxidatively converted to formic acid in aqueous systems.

Recent research has shown that POM catalysts can completely suppress the undesired total oxidation to CO2 under oxidative conditions when methanol is used as a (co-)solvent. Manipulating molecular catalysts such as POMs in solution by tuning the solvent properties and gas atmospheres introduces a new paradigm in homogeneous-catalysed biomass valorisation technologies. The proposed BioValCat project aims for developing this technology towards an industrial viable biomass valorisation process by laying the foundations for a scalable, safe and economic process for the oxidation of biomass to valuable carboxylic acid esters.
