Research Interests: My research focuses on understanding the response of ENSO to climate change as well as its possible role in abrupt climate change. I just completed an ENSO reconstruction spanning the last millennium from a sediment core located at the edge of the Pacific Warm Pool in the Indonesian Seas.

I am also interested in proxy development for paleoceanographic reconstructions, including revisiting established proxies such as the foraminiferal Mg/Ca paleothermometer. I am developing a correction procedure to take into account the effect of salinity on the incorporation of Mg into foraminifera tests.

I have applied this correction to existing records in the Indonesian Seas in order to better understand the role of this region on millennial to deglacial timescales.
