Research:

My research thus far has focused on understanding the patterns and mechanisms of climate change by using the ‘natural climate experiments of the past’ archived in lake and ocean sediments. For this, I use sediment geochemistry and geochemistry of biogenic carbonates such as, ostracod, gastropods and foraminifera. In particular, much of my research has focused on (1) Holocene Indian monsoon variability and its impact on the cultural evolution of the Bronze Age Indus Civilisation, (2) impact of Westerlies on Mediterranean climate during the late Quaternary period and, (3) South American Summer monsoon variability and associated Amazon river runoff. At EOS, I am involved in two projects: 1) developing Barium isotopes as a proxy for ocean productivity. 2) reconstructing late Quaternary climate of Southeast Asia using sediment cores from Kallang basin in Singapore. I am also collaborating with other groups at EOS for oxygen isotope stratigraphy and reconstruction of changes in the Indo-Pacific warm pool during the Quaternary period.
