About Me


I am a postdoctoral researcher in the Astronomy Unit at Queen Mary University of London, working with Dr. Tom Haworth. My research is on the chemistry of protoplanetary disks and what it tells us about how planets form.

Most of my work combines thermochemical models with (sub-)millimeter observations. I use and develop codes including DALI, PUFFIN, and my own network solver SIMBA, and I lead observing programmes on ALMA, SMA, and APEX. I am a member of the ALMA Large Programmes DECO and CHEER and of the Ariel consortium.

At the moment I am focused on externally irradiated disks: how ultraviolet radiation from nearby massive stars changes the gas and ice chemistry in a disk, which molecules trace that irradiation, and whether the environment a disk forms in leaves a lasting mark on the planets it produces. Earlier work includes chemical modelling of disk substructures, C/O ratios in Herbig disks, and sulphur and phosphorus chemistry.

I completed my PhD at UCL in 2024 with Dr. Mihkel Kama. Before astronomy I worked as a chef in London.
