Your Job:

Soil organic matter (SOM) and extracellular polymeric substances (EPS) play a central role in soil structure, water retention, nutrient cycling, and plant-microbe interactions. Their molecular behavior has profound effects on soil hydraulic properties and biome stability. However, despite advances in continuum modeling of soil and plant-water systems, the molecular-scale mechanisms underlying these processes remain poorly represented. This PhD project aims to fill that gap by using molecular simulations to quantify the interactions of SOM and EPS with water and minerals, and to connect these insights with larger-scale soil and plant models.

Perform molecular dynamics simulations to investigate interactions between soil organic matter (SOM), extracellular polymeric substances (EPS), water, and mineral surfaces
Parameterize, set up, and validate molecular-scale models of complex soil-relevant systems
Quantify structural, dynamical, and energetic properties governing water retention and soil hydraulic behavior
Analyze molecular simulation trajectories to derive mechanisms relevant to nutrient cycling and plant–microbe interactions
Translate molecular-scale findings into parameters and concepts usable in continuum-scale soil and plant-water models
Contribute to the development and documentation of reusable, open, and reproducible molecular simulation workflows
Collaborate with researchers working on soil physics, plant modeling, and multiscale simulation frameworks
Present research results at scientific meetings and publish findings in peer-reviewed journals

Your Profile:

Master’s degree (or equivalent) in computer science, applied mathematics, physics, engineering, biology, plant and agrosphere sciences, or another relevant natural science;
Strong background in Structural Bioinformatics and Molecular Dynamics (MD) simulations
Experience in setting up and running MD simulations. Previous usage of the AMBER suite is an asset
Knowledge on force fields structures and analyzing molecular trajectories to extract structural and energetic insights
Familiarity with assembling complex molecular systems and integrating heterogeneous data sources
Solid knowledge of Linux environments, including experience with HPC systems
Practical experience working with conda environments and Python scripting
Motivation to contribute to the development of an open-source molecular modeling platform for soil components
Hands-on experience in using differential calculus
Strong interest in using process-based mathematical modeling carbon cycling in soil-plant systems
