Hi! I’m a post-doctoral research associate at the Institute for Computing in Climate Science and the Atmosphere & Ocean Dynamics group at the University of Cambridge, working with Dr. Alison Ming. I am also a Bye-Fellow at Emmanuel College, Cambridge.

I am interested in all aspects of atmospheric fluid dynamics, with a particular focus on convection. My PhD addressed hydration of the tropical tropopause layer by overshooting deep convection. To get to grips with the mechanisms at play, we studied the idealised fluid dynamical problem of convective penetration of a buoyant plume into a stably stratified layer, using numerical simulations.

My current research focuses on coupling between large-scale stratospheric dynamics (the QBO) and convection in the troposphere, either directly via modification of the lower stratosphere or indirectly via modulation of patterns of convection such as the MJO.

Beyond my research, I have two main pastimes: rowing and amateur meteorology/cloudspotting. See here for my cloudspotting log.
