Research Interest

As a researcher, I am fascinated by the beauty and complexity of nature, especially the oceans and their impact on the entire planet. Climate change is unbalancing a highly complex system, with changes in the global water cycle already being felt. In the FreshOcean project, I am studying the effects of evaporation processes on the salinity and temperature of the ocean’s skin layer to better understand freshwater fluxes over the ocean. I hope that my research will contribute to a deeper understanding of the marine water cycle.
