I am a PhD student working with Prof. Christina Ravelo on tropical Pacific climate and climate variability during warm periods of the past five million years, using trace metals in foraminifera. I am particularly interested in reconstructing El Nino-Southern Oscillation (ENSO), and in combining proxy data and model results to determine mechanisms of ENSO change.
My first project, on ENSO in the Holocene, enables a test of ENSO’s sensitivity to changes in insolation, as indicated in models. My second project, on ENSO in the Pliocene, enables a test of ENSO’s dependence on sea-surface temperatures and thermocline depth, since these parameters were very different in the Pliocene than today.
My third project uses benthic foraminiferal B/Ca to constrain the effect of dissolution on Pliocene tropical Pacific Mg/Ca temperature records. This project will also generate data relevant for deep ocean circulation.
