    Current Research and Scholarly InterestsPermeability modelling on chemically compacted NaCl sieved samples, undergoing pressure-solution processes. The samples were imaged through X-ray microCT and the evolution of porosity in time was monitored and characterized. Permeability modelling through Lattice Boltzmann calculations will allow to understand the spatio-temporal evolution of dynamic transport properties during these processes.

    Current Research and Scholarly InterestsI focus on the formation of cementitious minerals through the pozzolanic reaction in both natural (cemented volcanic ashes) and man-made (Roman marine concrete) formations. My research aims to link the formation of these minerals with changes in the elastic and transport properties of the materials. This can be applied to hyper-alkaline geothermal systems, pozzolanic cements and future materials.

    Current Research and Scholarly InterestsI am a glaciologist with a deep interest for the physical processes that shape large ice sheets like Greenland and Antarctica. Currently the main focus of my research is on fast ice flow phenomena, in particular ice streams. These narrow corridors of fast flowing ice display a variety of complex behaviours, partly driven by external forcings - like climate -, and partly internally driven. The more theoretical side of my work seeks to understand the physical processes that govern these behaviours, in particular the spontaneous formation of ice streams out of an otherwise uniform flow, as well as the effects of climatic forcing on the internal dynamics of ice streams. I am also interested in placing observational constraints on the onset of fast ice flow, in particular through the interpretation of englacial layers. Previous lines of inquire include glacier surface hydrology, and the transition to turbulence in open channel flows over permeable beds.

    Current Research and Scholarly InterestsResearch
    I work to discover and understand the relationship between geophysical measurements and the rock and fluid properties that they sample in the Earth. My students and I have begun to understand the impact of rock type, porosity, pore fluids, temperature, and stress on seismic wave propagation and electromagnetic response. We are also working to quantify the links between geophysical measurements and the sedimentary and diagenetic processes that determine rock mineralogy and texture. Ultimately, this work allows us to better infer, from geophysical images, the composition and physical conditions at depth.

    I teach courses for graduate and undergraduate students on rock physics--the study of the physical properties of rocks and how they can be detected and mapped using seismic and electrical methods. This includes theory, laboratory measurements, and field data analysis. I also lead seminars in which students present and critique their ongoing research in rock physics.
