Research interests

I'm a climate scientist, and I'm passionate about applying physics to study climate and cloud processes, and in particular tropical convection. I'm interested in deep convection, clouds, tropical meteorology, microphysics, ocean-atmosphere interactions, mesoscale dynamics, monsoons, the Madden-Julian Oscillation, etc...

I aim to understand basic mechanisms to explain and understand how the Earth's climate behave.

At ZMT, I'm working with Prof. Jan Haerter on idealised simulations of the tropical rain band and of monsoons over an aquapatch, to understand the relationship between surface thermodynamic contrasts and precipitation intensity.

During my PhD, I was investigating what the sources of convective memory in idealised cloud-resolving simulations are, and how to apply convective memory in Global Climate Models. My project aimed at improving convective parameterizations in GCMs, and partly focused on convective memory coming from atmospheric cold pools.
