Profile

Research interests

My research focuses on better understanding clouds and convective processes. I combine observations, high-resolution numerical simulations and simple conceptual models to study how shallow cumulus clouds respond to changes in their large-scale environment, for example under climate change or across the diurnal cycle. I’m particularly interested in constraining the influence of rain and mesoscale convective organization on cloud feedbacks and thus climate projections. 

I received an ERC Starting Grant to elucidate how the evaporation of tiny rain drops influences our life on Earth (UHH press release). With Jan Kazil I organize the Cold Pool Model Intercomparison Project CP-MIP (weblink).
