My research interests are focused on the potential for quantification of modern and past natural processes from oceanographic observations, geological records and proxies (faunal, floral and geochemical), aiming to increase our understanding on present, past and prediction of future ocean-climate dynamics at various time scales.

My present research aims divide into three main themes

- 1. To explore the potential of various marine biota and different biotic & a-biotic compounds in marine sediments to quantitatively extract past physical/chemical ocean-climate parameters, with the aim to test and validate different (climate) models and scenarios. This theme involves how and where we can improve the precision and accuracy of proxy data that reflect (the variability of?) various ocean-climate parameters.

- 2. The role of carbon dioxide in ocean chemistry, its impact on marine calcifyers/calcification and ocean-climate change.

- 3. The oceanic heat budget, and in particular the export of heat, salt and water from low to high latitudes during glacial terminations and other periods of “rapid” climate change (e.g. during D/O events, the present-day).
