Area of research
Mineralogy and environmental sciences.

Specialised in
Reactive transport processes in geochemical systems.

HPC means for me
I am using HPC as a powerful microscope which provides me with atomic scale insight into the mechanism of fundamental geochemical processes taking place at fluid-mineral interfaces, inside of natural materials and so to validate the models suggested by experimental laboratory observations.

Molecular scale mechanism of vapor nucleation at mineral surface interface

Nowadays, computer simulation in geosciences have become an indispensable tool for testing hypothesis and predicting geochemical evolution of natural and engineered systems used for waste disposal, CO2 sequestration or geothermal energy harvesting. Coupled geochemical reactive transport modeling is often the only way to assess possible scenarios for their evolution over geological time scales. With the HPC infrastructure and IT services offered by CSCS, we are able to create high-fidelity digital twins of natural and engineered underground systems and apply these models for system design and subsequent environmental safety assessment.
