Postdoc: Weakly supervised ML-based Earth observation for climate extreme impact quantification

RISE will soon be officially opening applications for a postdoc position focused on developing an advanced Earth observation (EO) machine learning (ML) framework. The role involves identifying, geolocalizing, and quantitatively estimating the physical and socio-economic impacts of climate extremes such as floods, storms, wildfires, and landslides, using satellite image sequences.

A primary bottleneck in climate adaptation is that historical impact data is plagued by annotation sparsity: detailed pixel-level ground truth of damage is rare, while rich textual data from news, insurance disclosures, and humanitarian reports is unstructured, noisy, and spatially coarse. Furthermore, models trained in data-rich regions may face data distribution shifts when deployed across different geographic, infrastructural, or socio-economic contexts.

To address these challenges, the postdoc will develop annotation-efficient, weakly supervised ML-based Earth observation models that leverage unstructured data as a source of scalable distant supervision. The framework will incorporate uncertainty quantification techniques to ensure that the AI-derived impact estimates are reliable and actionable for decision-makers.

Core research task: Architecting data-efficient change detection for geospatial foundation models

Design and develop specialized, data-efficient architectural modules, built on top of frozen geospatial foundation models. The goal is to automatically detect and isolate large, extreme-event-related physical changes resulting from floods, storms, or wildfires, by modeling the contrast between pre- and post-event observations in heterogeneous, multi-sensor image sequences (Sentinel-1/2, Landsat/HLS, VIIRS/MODIS).

The development will focus on two major machine learning challenges:

  • Weak supervision under annotation sparsity: Engineering models to learn robust representations of rapid environmental transitions using minimal labeled instances and sparse, noisy text reports treated as distant supervision.
  • Distribution shifts and uncertainty quantification: Integrating strict geometric constraints directly into the adapter layers so the model can inherently flag high epistemic uncertainty when encountering out-of-distribution geographical features or unprecedented extreme-event severities.

About Climes

The Swedish Centre for Impacts of Climate Extremes (climes) is a research and training platform building an interdisciplinary field on how climate extremes affect people, ecosystems and infrastructure in a changing world. The Centre brings together physical, medical, social and engineering sciences to advance knowledge, shape the Swedish research landscape and strengthen societal resilience. Our work centres on three themes: compiling high-quality data on the impacts of climate extremes; analysing the physical–societal interactions that drive consequences; and developing policy-actionable scenarios to prepare for future extremes.

Who You Are

Beyond the specific requirements for each role, we are looking for curious, analytical individuals with a genuine passion for artificial intelligence and its potential to solve real-world problems, often in cross-disciplinary settings. You are a proactive problem-solver who thrives in a dynamic, collaborative environment. You are motivated by the opportunity to contribute to impactful research with tangible outcomes. Excellent communication skills in English (written and spoken) are required. Knowledge of Swedish is a plus but not a strict requirement.

Are We a Good Match?

At RISE, we strive to create a workplace where diverse expertise and backgrounds converge to solve societal challenges. We offer a dynamic research environment where you will work on exciting projects with strong connections to industry and societal needs. With us, you’ll have ample opportunities to learn, develop professionally, and contribute to meaningful innovation alongside experienced colleagues both within machine learning and application areas.
