Research Associate MOMENTplus- Integrated observation and modeling of CH4, CO2, and N2O in permafrost ecosystems § 28 Subsection 3 HmbHG

Institution: Faculty of Mathematics, Informatics and Natural Sciences, Department of Earth System Sciences

Salary level: EGR. 13 TV-L

Start date: 01.05.2026, fixed for a period of three years (This is a fixed-term contract in accordance with Section 2 of the academic fixed-term labor contract act [Wissenschaftszeitvertragsgesetz, WissZeitVG]).

Application deadline: 2026-02-28

Scope of work: part-time

Weekly hours: 66 % of standard work hours per week

Your responsibilities

Duties include academic services in the project named above. Research associates may also pursue further academic qualifications outside of their work responsibilities. They may also pursue doctoral studies outside of working duties.

We are looking for a highly motivated PhD student to work on the MOMENTplus project (). The project aims to improve our understanding of the interaction between biogeochemical processes in permafrost-affected terrestrial ecosystems, which are affected by climate change. This knowledge will then be used to improve models that are projecting CO₂, CH₄ and N₂O fluxes in Arctic landscapes. MOMENTplus is a collaborative project involving seven German research institutions.

The PhD candidate will contribute to Subproject 1, which focuses on the influence of vegetation, microbial communities and soil properties on carbon storage and greenhouse gas fluxes in a changing Arctic. The candidate will be responsible for planning, conducting and evaluating field studies in the Arctic within this project. The focus will be on the impact of climate change on biogeochemical processes and greenhouse gas fluxes in permafrost-affected soils. Furthermore, laboratory experiments will need to be developed to gain detailed insight into the impact of environmental parameters and vegetation on the microbial turnover of CO₂, CH₄ and N₂O. During fieldwork and laboratory work, the candidate will collaborate closely with team and project members. Scientific results must be presented at project meetings and conferences, as well as in scientific publications.

This position is within the “Dynamics of Soil Processes” working group at the University of Hamburg, which is a dynamic and growing group of field scientists and modellers who focus their research on Arctic ecosystems and related climate feedbacks. PhD candidates are members of our graduate school, which aims to support young academics throughout their training. Further information can be found at this link: .
