PhD Researcher (f/m/x) in In4Nile PhD-Cohort: Monitoring water quality impacts using NLP and LLMs (f/m/x)
The job
In the PhD cohort "In4Nile" - Advancing Water Quality Information in the Nile River Basin, we offer four PhD Positions. In4NILE addresses the limited availability of water quality information in the Nile basin by developing and applying low-cost sampling techniques, mining of existing open (geo)datasets, exploring the use of unstructured data sources through natural language processing, and by developing basin-scale, multi-pollutant spatially explicit water quality models. Building on this framework, the PhD candidate (f/m/x) will leverage the increasing amount of unstructured text data and advances in natural language processing (NLP), large language models (LLMs), and machine learning to extract, analyze, and spatialize pollution-related knowledge. Traditional monitoring approaches, which rely on sparse in situ measurements, offer only a partial view of how citizens and stakeholders perceive the impacts of pollution. In contrast, text sources such as news and institutional documents provide information on how pollution is experienced, debated, and understood by local communities.
