I am a geochemist with an environmental justice focus. I'm interested in how the chemical form of contaminants informs landscape-scale contaminant transport, whether towards plant roots, other ecological receptors, or groundwater. I combine work at multiple scales, from field to nano, to investigate contaminant cycling and determine sustainable soil remediation methods that a variety of stakeholders, from urban agricultural groups to municipalities, can use to solve environmental problems and increase community health.
In my postdoctoral work, I gain disciplinary breadth and learn new skills investigating iron nanoparticle transport in marine systems. Iron emitted from hydrothermal vents on the seafloor has been hypothesized to contribute to up to 30% of net primary production in parts of the ocean, but geochemical common sense says this iron should crash out to ocean floor. I investigate how this iron stays suspended to reach the open ocean and, eventually, surface phytoplankton communities.
