Geographically, my current research areas include the Bay of Bengal, Central Asia, eastern equatorial Atlantic and the Mozambique Channel.
I use marine sediments and cave deposits to decipher forcings and feedback mechanisms of changes in hydroclimate, sea surface temperature, and ocean circulation.
My lab analyzes stable isotopes (d18O, d13C) and trace elements in foraminiferal calcite and cave deposits. We use well-dated and highly resolved time-series to establish records of past climate changes.
My lab works also on several projects to establish and refine proxy-calibrations. In collaboration with my post-doc Will Gray and my colleague Professor David W. Lea, I work on constraining the salinity and temperature effect on Mg/Ca of Globigerinoides ruber (white) and improving the application of Mg/Ca as SST proxy. To achieve these goal we using published and unpublished Mg/Ca data analyzed in samples from plankton tows and sediment traps (see salinity and sample map)
