CLIMATE RECONSTRUCTION: My current research is focused on two primary objectives: (1) developing the use of massive coral skeletons for paleoclimatic reconstruction, particularly in the Southwest Pacific and Indonesia, and (2) developing sediment records of Western Pacific Warm Pool climate and Indonesian Oceanographic Throughflow variability. Modern coral skeletons can provide near-monthly resolved and continuous records of changing oceanographic conditions over the last 500+ years. Deep sea sediment cores can extend the paleoclimatic record back Millions of years.  In addition to my research using Sulu Sea and Indonesian sediment cores, I participated on the Integrated Ocean Discovery Program Leg 363 in the Western Pacific in 2016 and we are currently analyzing sediment cores from Sites 1486 and 1487 on the New Guinea margin.  See:
