Outline Activities
My research interests are marine biogeochemical cycles, carbonate production of coral reefs, evolution of coral-algal symbiosis, and their connections to global environmental changes through the geological timescale. My approach is reconstruction of environmental and metabolic records in modern and fossil coral skeletons.
