Research Interests

My research interests lay at the interface between ocean engineering and geochemical modeling. Previous research produced an in-situ conductivity sensor for high temperature hydrothermal vents. This instrument is now included as part of the backbone of two seafloor observatories in the Northeast Pacific: Neptune Canada and Regional Scale Nodes.

More recently, work supported by Ridge 2000 led to the construction of transport and geochemical models and novel combinations thereof. These models have been used to investigate the chemical makeup of microbial habitats in the subsurface of mid-ocean ridge hydrothermal systems.

The ongoing refinement and application of computational and engineering tools from past work and my development of new methods fall under the broader study of Earth Ocean Interactions. Here we collectively focus on painting a more quantitative and comprehensive picture of the physical, chemical, biological, and geological, interactions at tectonic plate margins.
