Postdoctoral Position in Ecological Knowledge-Guided Machine Learning - Aarhus University

A 2.5-year position as Postdoctoral Researcher within the field of Freshwater Ecology is available at the Department of Ecoscience, Aarhus University.  The expected start date is 1st of September 2026 or as soon as possible thereafter. The position seeks to strengthen and complement the Department’s ongoing activities in freshwater ecology, particularly aquatic ecosystem modelling and water quality modelling, with focus on Knowledge-Guided Machine Learning. The position is a rewarding opportunity to be integrated in an excellent freshwater group. The department’s research and advisory activities are project-based with a solid tradition in cross-disciplinary research and international collaboration.

The postdoctoral researcher will work with Dr. Robert Ladwig on developing hybrid models that integrate limnological knowledge into machine learning models following the paradigm of Knowledge-Guided Machine Learning (KGML). A specific aim is to further develop the methodology of modular compositional learning, which combines multiple parts, either process-based or machine learning, into one framework for better projections. To get more data for model verification, we are deploying novel monitoring buoys all over Denmark.

The project provides training and growth opportunities in AI. Candidates who have strong interest in machine learning, but minimal experience, are encouraged to apply. You will work closely within an interdisciplinary team of computational and applied scientists, and with many international partners.

The ideal candidate should have:

• A PhD in environmental engineering, ecology, environmental science, biology, data science, computer science, or a closely related field
• Knowledge of freshwater ecology and/or physical limnology
• Experience with numerical modelling
• Experience with programming languages, esp. Python, and familiarity in NumPy, SciPy and Pandas
• Experience with scientific programming 
• Experience with scientific writing
• Excellent written and spoken English
• Interest in deep learning and Knowledge-Guided Machine Learning
• Interest in scikit-learn, PyTorch and TensorFlow

Personal qualifications required include the ability to work closely with other researchers/groups within the Department as well as with external end users, and the ability to collaborate and build relationships. Teamwork and cross-disciplinary research are key elements for the Institute.

The Department of Ecoscience offers:

• a well-developed research infrastructure, laboratories and access to shared equipment
• Opportunities for interdisciplinary collaboration across Ecosciences focus groups and QGG
• Mentorship and support in developing independent research directions
• Support for grant writing and professional development
• a workplace characterised by professionalism, equality and a healthy work-life balance.
