Personal profile
Research interests
My primary scientific interest is gas outflows accelerated by accreting supermassive black holes (SMBHs) in the centres of galaxies (known as active galactic nuclei, or AGN) and their impact on their host galaxies. Despite being commonly considered to play a crucial role in how galaxies evolve, deriving their key properties from observational data is difficult, and involves significant uncertainties. Therefore, a large focus of my work is to develop and use precise diagnostics of outflow properties in order to determine their true importance in galaxy evolution.
I am a member of the Survey Working Group (SWG) for the WEAVE-LOFAR survey, which is due to start in 2025. In addition to performing scientific analysis with data produced by the survey, I am actively involved in determing the survey strategy, planning observations, and writing key software needed to analyse the data.
