About my research
I'm a post-doc at the Max-Planck Institute for Meteorology. My current research is focused on answering how the tropics precipitate by using an Earth-system model, which can explicitly represent storm and ocean eddies. I'm interested in understanding the role of different surface conditions on the tropical rainbelt, in particular, why land makes it easy to get the structure of the terrestrial tropical rianbelt in a model explicitly representing storms.
My research also focuses on understanding the impact of precipitation on ocean stratification. Simulations resolving convective storms and ocean eddies show that precipitation can play a role in how surface currents can feel the wind forcing.
