Current Research

My current research harness a joint-interpretation approach, using a surface-towed controlled-source electromagnetic (CSEM) system in conjunction with high-resolution multi-beam for seafloor mapping & water column scanning, as well as seismic and rock physics methods; for 2D/3D resistivity imaging of submarine groundwater systems along the continental shelf offshore Hawai'i volcanic islands.
