My master's work focused on the Indirect Effect, whereby cloud-aerosol interactions lead to a change in the cloud's radiative properties, including lifetime, extent, and albedo. The warm cloud shortwave Indirect Effect can be decomposed into an approximate sum of its parts, the albedo and lifetime effects. Evaluating the individual components of the Indirect Effect in cloud and environmental regimes, established using reanalysis and observations, allows further insight into the physical controls of cloud sensitivity.

My current work focuses on comparing the effects of aerosol versus other controls that may modulate a cloud's physical and thermodynamic structure. In a changing Earth system, understanding how not just the environment, but cloud feedbacks induced by climate change, is important for constraining a climate sensitivity. Comparing and contrasting how strength of the Indirect Effect against other controls like precipitation susceptibility, stability, and vertical structure, is important to understand the role of clouds in the Earth system.

In my free time I enjoy reading, watching documentaries by Louis Theroux, and being outdoors.
