Do you want to do research on causal-informed machine learning methods for climate modelling? 

If you are establishing a career as a researcher in machine learning and are motivated to work with the latest generative models for climate modelling, we can offer you a strong foundation. We seek a highly motivated and talented PhD student to join our group at DTU Compute, offering a fully funded PhD scholarship (3-year employment) in a vibrant interdisciplinary research environment. 

The position is part of the research project “IcyAlert – Intelligent Climate Early Warning Alert for Arctic Ice-Free Summers”, funded under the NNF Grand AI Challenge programme. 

You will become part of an enthusiastic team working closely with collaborators at DMI (Danish Meteorological Institute) and RMI (Royal Meteorological Institute of Belgium) to advance neural network-based methods for climate modelling. 

About IcyAlert 
The goal of the IcyAlert project is to provide robust predictions of Arctic ice-free summers at multi-seasonal time scales and their potential climate impacts under various warming scenarios, supporting sustainable climate solutions. Arctic summer sea ice extent has declined by nearly 13% per decade since 1979, accompanied by a 90% reduction of older ice. These changes pose increasing risks to ecosystems, food security, navigation, etc. 

By combining dynamical models, satellite data, causal analysis, and explainable AI, IcyAlert will identify critical thresholds, enhance prediction accuracy, and generate automated alerts for seasonal Arctic and extratropical climate events. Using Gefion in the project will be essential for analysing complex datasets and training advanced large-scale predictive models. This interdisciplinary initiative brings together experts in AI, climate modelling, and causal analysis to enhance preparedness for an ice-free Arctic. 

Responsibilities and qualifications  
This PhD project will focus on developing causal-informed machine learning (ML) methods to perform Arctic sea-ice predictions at multi-seasonal timescale. You will work with datasets such as CMIP6, ERA5 and CARRA2. There will be three subprojects: 1) quantify causal links between winter climate drivers (November-April) and summer Arctic sea ice area (May-October), 2) develop causal-informed AI/ML models for ice-free Arctic predictor, 3) generate probabilistic predictions of ice-free conditions from 2030 to 2050. 

You should have the following required skills: 

• Have a strong background/interest in causal modelling (Math/Physics/Computer Science background).
• Demonstrated experience in machine learning, including some exposure to graph modelling and diffusion models. 
• Experience with implementing machine learning methods in Python using Pytorch or Flax. 
• Familiarity with managing larger code bases and training models on HPC systems. 
• Familiarity with climate modelling is a big plus. 
• High level of motivation and creative problem-solving skills.   
• Excellent communication and writing skills in English.

You must have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.

Approval and Enrolment 
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU’s rules for the PhD education. 

Assessment
The assessment of the applicants will be made by Associate Professor Tommy Sonne Alstrøm and colleagues in the IcyAlert project.
