PhD / Postdoc / RSE Position in the AqQua Project: Building a Foundation Model of Aquatic Life

Employer

Max Delbrück Center for Molecular Medicine

Location

Berlin (DE)

Salary

TVöD E13

Closing date

30 May 2025

Build large-scale AI to map and monitor plankton biodiversity, ecosystem health and carbon flux, facilitating decision‑making in the face of climate change. Hosted at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association, founded in 1992, today inspiring and nurturing a diverse talent pool of 1,800 people from over 70 countries. We are 90 percent funded by the German federal government and 10 percent by the state of Berlin.

Job Description

Human well-being to a large extent depends on aquatic life: Organic matter formed by plankton sustainably sequesters vast amounts of carbon from the atmosphere in the ocean’s interior. The efficiency of this so‑called biological carbon pump is likely altered by climate changes that affect planktonic diversity. The climate change-induced reduction of food web efficiency further directly impacts oceanic fish resources that play a major role in human nutrition. The critical role of aquatic life in biogeochemical cycles, for climate regulation, conservation of aquatic biodiversity and human nutrition mandates precise mapping and monitoring, to provide essential knowledge and to serve decision‑making in the face of global change, e.g. with respect to emerging carbon dioxide removal techniques.

To this end, distributed pelagic imaging techniques enable the sustained observation of aquatic life and its debris, comprehensively covering the earth’s water bodies down to the bottom of the deep sea. The Aquatic Life Foundation Project (AqQua) will, for the first time, combine billions of images acquired with a variety of devices across the globe for large-scale training of a foundational pelagic imaging model, which will be fine-tuned for species classification, trait extraction, and particulate organic carbon estimation. The model will allow to establish global maps of species biodiversity, ecosystem status, and carbon flux at unprecedented accuracy and granularity, thereby generating a fundamental understanding of marine and freshwater life in times of global change.

Billions of images are available for this project, with high diversity across modalities and geolocations. Several unique aspects of pelagic imaging call for enriching self-supervised learning paradigms as well as interactive data- and model exploration with domain knowledge towards optimal performance in real-world generalization scenarios.

AqQua is a large-scale collaborative research project led by the MDC/Helmholtz Imaging, GEOMAR, Hereon and FZJ, fully committed to Open Science.

We are looking for a PhD student or Postdoc or Research Software Engineer to join our highly vibrant and uniquely interdisciplinary team of AI and domain experts dedicated to the cause. Potential responsibilities for the position:

Explore, benchmark and devise self-supervised learning paradigms for plankton imagery

Engineer advanced architectural components and workflows for efficient and effective foundation model training and fine-tuning

Devise data curation and balancing schemes

Rigorously assess model scaling and generalization behavior

Roll out the model to the global user community

Requirements

PhD or MSc in computer science, physics, mathematics or a related discipline

Experience with large-scale HPC

We offer

International working environment with communication in English and German

Interesting career opportunities and a range of opportunities for further qualification and training

Compatibility of family and career certified by the workandfamily audit ("berufundfamilie audit")

Support for "New Berliners" through the MDC Welcome & Family Office

You also benefit from:

A remuneration in accordance with the collective agreement for the federal public service (TVöD Bund), including additional company pension schemes

Flexible working hours

The possibility of mobile working

Salary

Remuneration will be according to the TVöD Bund pay category E 13, depending on qualification.

Employment volume

Full time

Desired starting date

May 1, 2025

Limitation

Fixed term

The position is limited to 3 years.

Application period
