My research interests focuses on the analysis and modeling of the hydrological cycle of the South Asian summer monsoon from intraseasonal to decadal time-scales, with focus on land-atmosphere and air-sea interactions. I am also interested in studying the influence of the Himalayas and the Tibetan Plateau in the development and evolution of the summer monsoon. I am currently working on the improvement of the understanding of the mechanisms of aerosols-driven changes in regional hydroclimate and circulation over South Asia and other regions of the world with the GFDL model.
