Professional Interests


My work is currently focused on the use of imaging as a tool to characterize tight porous media. My imaging efforts toggle from nano, to micro and meso characterization using optical and X-ray imaging techniques to achieve insightful knowledge on the rock-fluid behavior of these systems. The overarching objective is to bridge scales from the nano resolution scaled images obtained from my experiments at SLAC, to micro-scale resolved at the SNSF facilities, to meso-scale imaging performed with medical CT scanners.

I am also involved in experimental investigation of enhanced oil recovery methods (such as CO2 or hot water injection) targeted at low permeability resources. My research explores the impact of different variables related to the recovery method (such as temperature, injection mode, miscibility conditions, injected fluid) and/or rock properties and how these are altered (wettability, porosity and permeability) and how they affect the effectiveness of the total oil recovered. Experiments usually involve CT scan imaging of the samples during the processes and the use of simulator-based models to represent and duplicate experimental results
