Research areas
I'm a structural / data geologist with many years of experience working (and teaching) in different structural and exploration (outcrops) terrains with all forms of geoscientific data, including remote sensing, drone imagery, geomechanical/numerical data, microstructural data etc., for fault and/fracture network characterization. In particular, my research utilizes GIS tools and remote sensing to study the interaction of fracture networks in diverse rocks, fracture topology, flow in fractures under changing stress conditions, and geomechanical simulations of fracture networks.
