One of Professor Ray's main areas of work is multi-scale modeling. She cooperates with geoscientists to find out more about the composition and structure of soils. “The microstructure of the soil has a direct influence on its macroscopic behavior. One focus of my work is therefore to build bridges between these two scales,” explains Professor Ray. As the composition of soils is not static, but constantly changing, this places particular demands on multi-scale modeling of issues in this area. Soil plays an important role in questions of energy, sustainability, climate and the environment - as a reservoir for water and carbon and as a habitat for microorganisms. For example, multiscale modeling provides the basis for simulating the absorption of water and nutrients by roots as well as ideal living conditions for microorganisms - also as a basis of knowledge for combating hunger.

Interpore 2026

In May, the 18th Interpore Conference took place in Nantes, France. Prof. Dr. Nadja Ray (Chair of Geomatics and Geomathematics at MIDS) attended on behalf of KU. In addition to participating in the conference, Prof. Ray also organized a mini-symposium and two poster presentations. The steering committee of the German chapter also met, and there were many opportunities for professional exchange.

Processes in porous media — including flow, transport, deformation, and reactions — are central to applications in energy, environment, and advanced materials. Experiments and field observations are often costly or infeasible, making mathematical modeling and simulation essential.

Challenges arise from strong heterogeneity, multiscale and multiphysics interactions, or phase transitions. This minisymposium invites contributions on:

The minisymposium aims to foster exchange on methodologies and applications for porous media in the geosciences at both laboratory and field scales, as well as on bridging across scales.
