The overarching theme of my research is trace-metal interactions at mineral surfaces. My current primary research is investigating weathering reactions along bedrock fractures and materials of various stages of weathering. This includes drilled bedrock cores, landslide-exposed rock, saprock and waters (surface, ground and precipitation) in tropical watersheds. This research, based at the Puerto Rican Critical Zone Observatory, is of integral importance to many global cycles as tropical environments contribute 50% of the water, 38% of the dissolved ions, and 65% of the dissolved Si to the world’s oceans and thus are disproportionately important to global weathering fluxes.
