I am a geochemist with an environmental justice focus. My low-temperature geochemistry research program investigates contaminant cycling in urban ecosystems. I focus on three areas of research: 1) developing sustainable and accessible soil remediation methods; 2) determining distributions of contaminants in urban soils; 3) investigating contaminant uptake in food crops. My work reveals hidden parts of geochemical cycles using community-based field studies, mesoscale work under controlled conditions, and advanced nano- and micro-scale analytical approaches.
In my postdoctoral work, I gain disciplinary breadth and learn new skill investigating iron nanoparticle transport in marine systems. Iron emitted from hydrothermal vents on the seafloor has been hypothesized to contribute 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 open ocean waters and, eventually, the surface.
