The body of my research activities is devoted to the long-term evolution of, and the interaction between, the coupled land-ocean-atmosphere climate phenomena such as the Australasian monsoon systems, the Indian Ocean Dipole, and El Niño-Southern Oscillation. To this end, I make use of various proxies and models, together with my partners, to reconstruct and to simulate past changes of the hydrological cycle: ocean circulation and thermal structure of the water column, salinity, terrestrial vegetation, rainfall, and runoff, as well as atmospheric zonal and meridional circulations.
