Research Interests

My interest is to improve the understanding of Indian Ocean climatology, the Indo-Asian and African monsoon dynamics: the forcing-response relationship at orbital and glacial-interglacial time scale. I have a special interest in the strong western boundary current of South Africa, i.e the Agulhas current, its variability, global climatic impact and its effect on regional African climate. Further research interests include the development and the comparison of different quantitative sea surface temperature and salinity reconstruction tools.
I have strong interests in data-climate model comparisons. I perform climate simulations of stable isotopes in the three-dimensional coupled numerical model of intermediate complexity iLOVECLIM for specific time periods. The results are integrated with paleoclimatic reconstructions to evaluate the model and improved our understanding of climate proxies, isotopic processes and the climate system. I also realize syntheses of global paleoclimatic data for stable isotopes in continental and marine realms.
I have recent interests for African past climate and its link to Hominin evolution.
