I'm an experimental petrologist.

My primary research is focused on the understanding of mantle melting and basalt genesis processes. This part of my research is articulated on the role of mantle heterogeneities and magma-rock interactions in the genesis of basalt. I discuss this topic via an experimental approach coupled to thermodynamical modeling.

After I joined the Lamont-Doherty Earth Observatory, I added fluid-rock interactions to my research program. I work to constrain the conditions for witch reactive cracking may happen. Reaction-driven cracking could be important in geological capture and storage of CO2 as it is essential for in situ mineral carbonation methods to maintain or enhance permeability and reactive surface area.
