About Me

My research focuses on (but is not limited to) the characterization of the fluid transport in porous media, the use of transient gas tracers to study physical processes in the solid earth, and the application of dissolved gas/solid species in the pore water of unconsolidated sediments as proxies for environmental reconstruction.

For a complete list of my publications and conference contributions please refer to my personal website.
