My research involves reconstructing climate variability over the past several hundred years using coral archives and proxies. Currently, I am focusing on reconstructing sea surface temperature (SST), terrestrial runoff, and sea surface salinity (SSS) using Sr/Ca, Ba/Ca and stable oxygen isotopes as proxies, respectively. I may also examine changes in ocean circulation in certain regions using Δ14C. Using this wealth of proxies, I hope to study variability in larger climate systems, such as the Southeast Asian monsoons and the El Niño Southern Oscillation (ENSO), which has global impacts. Changes in such systems influence local economies and populations including agriculture, fisheries, and tourism by impacting storm frequency, sea level rise, and rainfall patterns. By improving our understanding of past changes, we can provide more insight into changes that may happen in the future.
