Spatially-resolved galaxy evolution
I'm interested in the formation and evolution of galaxies, ranging from dwarf to giant galaxies within the local to high-redshift Universe. I investigate the internal (mass, angular momentum) and environmental factors responsible for galaxy diversity in properties such as morphology, chemical content and dark matter content, mapping their evolution over cosmic time.

Spatially-resolved Galaxy Evolution
How do the irregular, clumpy, highly-starforming galaxies we see in the distant, long-ago universe transform to the familiar elliptical and spiral galaxies we see in the present-day universe? You could investigate new ways to understand high-redshift galaxies based on fundamental physical properties such as angular momentum or chemical abundance.
How typical or unusual is our Local Group of galaxies, having two massive spiral galaxies each with a plane of satellite dwarf galaxies? You could determine how common the Local Group is by using equitable methods to study the fundamental physical properties of its dwarfs and the dwarfs of observed and simulated groups which resemble the Local Group.
There are several projects available, all focusing on disentangling galaxy evolution with the technology of integral field spectroscopy (IFS). Our team is part of world-leading IFS surveys (Hector Galaxy Survey, MAGPI Survey, Dwarfs in Local Group Analogues, AGEL, WALLABY) and is working to map the properties of thousands of galaxies in 3D (two spatial and one spectral dimensions). We will use these data to understand the connection between the internal and external properties of galaxies of all sizes and shapes and at all distances.
