Hi! I’m a PhD student in the Atmosphere & Ocean Dynamics group at the University of Cambridge. My supervisors are Prof. Peter Haynes and Prof. John Taylor.

My current reserach focus is the problem of stratospheric hydration by convective overshoots in the tropics. To get to grips with the mechanisms at play, we study the idealised fluid dynamical problem of convective penetration of a buoyant plume into a stably stratified layer, using numerical simulations. Aside from my PhD project, my research interests cover a wide range of atmospheric phenomena, from large scales (QBO, internal gravity waves, teleconnections) to small (turbulent mixing, convection).

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