• Characterization of the pore structure of materials. Characterization of the pore structure of single and dual porosity materials. Calculation of the transport properties of porous materials from pore structure parameters.
• Multiphase transport in porous media. Transient and steady-state immiscible and miscible displacement experiments in porous media with applications to enhanced oil recovery, CO₂ storage, and soil contamination. Estimation of the relative permeability functions / capillary pressure curve / hydrodynamic dispersion coefficients of porous media with inverse modelling. Development of hierarchical models to up-scale the transport properties of heterogeneous porous media.
• Carbon dioxide storage in saline aquifers. Experimental investigation and numerical modeling of CO₂ dissolution in aquifers, correlation of the dissolution rate with multi-scale heterogeneities, effects of CO₂ leakages from storage sites on the quality of water in overlying aquifers.
• Soil & groundwater contamination. Soil column experiments and macroscopic simulation of the fate of organic pollutants in the subsurface (e.g. advection/ dispersion/ sorption/ biodegradation of pesticides in groundwater). Chemical characterization of contaminated soils and groundwater with chromatographic techniques (GC-MS, GC-FID, Ion-chromatography).
• Application of advanced oxidation processes to the treatment of contaminated soil and wastewater. Design, lab-scale testing and numerical modeling of cost-effective and sustainable methods for soil remediation (e.g. non-thermal plasma), and wastewater treatment (e.g. nanoparticle-based photocatalytic processes).
• In situ soil and groundwater remediation.Lab-scale testing, numerical modeling and field-scale application of technologies used for the in situ remediation of the vadoze and saturated zones of the subsurface (e.g. steam injection, bioventing, injection of suspensions of zero valent iron nano-particles).
• Improved oil and gas recovery. High pressure routine and special core analysis of reservoir rocks, identification of multiphase flow / transport mechanisms in reservoir rocks, numerical modeling of enhanced oil recovery by surfactants, pore-to-core scale transport properties of unconventional tight reservoirs (e.g. shale gas).
• Nanomaterial-based environmental technologies. Investigation of the capacity of functionalized nanoparticles (CNTs, nZVI) to remove various types of pollutants (e.g. pesticides, hydrocarbons, heavy metals) from surface water, groundwater, and soil.
• Biomass valorization. Utilization of agricultural wastes for the development of low cost hybrid adsorbents capable to remove “cocktails” of multi-species pollutants (e.g. heavy metals, pesticides, PAHs, etc) from wastewater.
