Unser Profil

The research focus at the Chair CG³ of RWTH Aachen University lies in applied geophysics and numerical simulation in the geosciences. We develop innovative approaches for the characterisation and prediction of subsurface processes, combining geological modelling, data integration, artificial intelligence, and uncertainty quantification.

We are actively involved in the development of scientific open-source software (e.g. GemPy) and work at the interface of geoscience, computational science, and machine learning.

In teaching, we contribute to the B.Sc./M.Sc. programmes „Applied Geosciences“ and „Georesources Management“ of RWTH Aachen (www.fgeo.rwth-aachen.de) as well as to the international Joint M.Sc. programme „Applied Geophysics“, which we offer together with TU Delft and ETH Zurich (www.idealeague.org/geophysics).

Ihr Profil

You hold an above-average university degree (Master or equivalent) in Geosciences, Data Science, Computer Science, or a related field.

You have a strong interest in AI, digital geology, and knowledge representation, and ideally bring:

programming experience (e.g. Python)
interest in semantic technologies and/or machine learning
ability to work independently and in an interdisciplinary team
strong communication skills in English

Knowledge of German is an advantage.

Ihre Aufgaben

The position is embedded in the BMFTR-funded project DTXplore, which develops a digital twin framework for mineral exploration, integrating geological knowledge, geophysical data, and AI-supported modelling across multiple spatial scales.

This PhD project focuses on the development of ontology-driven AI approaches for mineral systems modelling.

Your tasks include:

Development of a domain ontology for mineral systems, covering lithology, structure, alteration, geochemistry, and mineralization
Integration of structured geological knowledge into AI-assisted 3D geological modelling workflows
Development of retrieval-augmented generation (RAG) approaches to support digital twin modelling
Application of natural language processing (NLP) to extract information from geological reports, maps, and scientific literature
Integration of extracted knowledge into uncertainty-aware geological models
Validation of methods using case studies in Germany and Australia
Collaborative research-stays in Australia
Publication of results in peer-reviewed journals and presentation at international conferences

The position offers the opportunity to establish an independent research profile at the interface of geosciences, AI, and knowledge representation, with the goal of completing a doctoral degree. In addition, participation in teaching within our B.Sc. and M.Sc. programmes (lectures, exercises, supervision of theses) is welcome.
