Our Research

Research Themes

Our group studies the physics of water, solutes, and interfaces in porous media, with a focus on geoelectrical methods and soil-plant processes.

Interfacial Geoelectrics in Porous Media

We use spectral induced polarization (SIP) to investigate interfacial properties, electrical double-layer effects, and contaminant-mineral-fluid interactions across scales.

Soil-Plant Processes in the Rhizosphere

We study how roots, exudates, and plant hydraulics shape water and solute transport, and how these processes appear in geoelectrical measurements.

Theme 1: Geoelectrical Properties of Porous Media

Interfacial Properties and SIP

We investigate how interfacial processes control the electrical behavior of soils and sediments. A central question in our work is how pore-scale and electrical double-layer dynamics shape measurable SIP signatures.

Contaminants, Reactive Systems, and Remediation

We use SIP and related geoelectrical methods to quantify interactions between organic pollutants, mineral surfaces, and reactive amendments, with the goal of non-invasive monitoring of fate, transport, and remediation performance.

Theme 2: Soil-Plant Interactions

Rhizosphere Transport and Root-Soil Coupling

We study how roots and root exudates modify rhizosphere properties and influence water and solute movement in saturated and unsaturated soils.

Root Function and Crop Stress Responses

Using hydrogeophysics and process-based interpretation, we investigate drought and salinity stress, root architecture, and below-ground controls on plant performance.
