About

I am a professor of Astrophysics in the Department of Physics & Astronomy at University College London (UCL).

My research programme is centered around the question of what regulates the growth and evolution of galaxies. In particular, I use radio telescope to make a census of the cold gas contents of large sample of galaxies; understanding when, where and how galaxies efficiently form stars out of gas is key in identifying the mechanism driving their evolution.

Recent highlights

Publication highlights

10.2022 Is it possible to derive reliable cold gas masses from the information contained in optical spectra? PhD student Dirk Scholte answers this question in this new study based on xCOLDGASS, SDSS and PHANGS data and photoionisation modeling.
04.2022 In a follow up to last year's paper, PhD student Lucy Hogarth used kinematic evidence to show how disc instabilities (especially bars) may be linked to large scale ionised gas outflows. Read the new paper here.
02.2022 New article for Annual Reviews of Astronomy & Astrophysics, about the cold interstellar medium of galaxies in the local universe, setting its importance in the galaxy evolution context. Published article available here.
02.2021 We released a new and accurate determination of the abundance of cold gas at z~0 and present the xCOLD GASS-derived molecular gas mass function, in a paper by recent graduate Tom Fletcher.
