Research Associate for the Project “Biota-Mediated Effects on Carbon Cycling in Estuaries (RTG2530) – Postdoc project PP1: Ecological network synthesis across ecosystem boundaries” § 28 Subsection 3 HmbHG

Institution: Faculty of Mathematics, Informatics and Natural Sciences, Department of Biology, Institute of Cell and Systems Biology of Animals

Salary level: EGR. 13 TV-L

Start date: 01.04.2026, fixed until 31.03.2029 (This is a fixed-term contract in accordance with Section 2 of the academic fixed-term labor contract act [Wissenschaftszeitvertragsgesetz, WissZeitVG]).

Application deadline: 2026-03-06

Scope of work: full-time position suitable for part-time

Your responsibilities

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

The research associate (postdoc) will be a member of the DFG funded Research Training Group 2530 (Biota-mediated effects on Carbon cycling in Estuaries). For this task, you will join the research group of Animal Network Ecology as a postdoctoral researcher. In your research, you will synthesise, integrate and generalise the knowledge about biotic interactions in estuaries gained in the RTG and beyond. Specifically, to tackle the complexity of ecological interactions across subsystems, you will construct interaction networks that synthesise the knowledge of relevant ecological interactions within and between terrestrial and aquatic realms of the Elbe Estuary compiled in the three cohorts of doctoral researchers of RTG2530, spanning a wide range of taxonomic units, functional traits, habitats and interaction types. As a data steward, you will enhance the overall data management and archiving of the RTG as a basis for your reproducible work. Using multilayer network, network of networks and metanetwork approaches, you will describe the connections within and between subsystems and explore approaches for estimating the quantitative structure and function of these networks and identify key connectors. The compilation of an integrative network description will pave the way for guiding the inclusion of so far neglected processes, traits and taxa into future ecosystem models. You will closely collaborate with other doctoral and postdoctoral researchers to advance process-based dynamic models and study trophic interactions of animals at the land-water interface.

Your profile

A university degree in a relevant field, plus doctorate.

A PhD/doctorate in Ecology or a related discipline.

Essential:

• strong quantitative skills: data analysis, data management, modeling, mathematics
• at least some familiarity with network analysis (or similar approaches)

• open-minded, critically thinking and quality-oriented attitude

Advantageous:

• experience/knowledge about both, aquatic and terrestrial ecology
• knowledge about ecosystem ecology/biogeochemistry
• knowledge of microbial ecology, plant ecology and animal ecology
