Research interests
My research is focused on the formation history of nearby galaxies using planetary nebulae as chemodynamical tracers (mainly the great Andromeda galaxy). At Herts, I will work on understanding chemical enrichment in both nearby and higher redshift galaxies. I have previously also worked on galactic open cluster structure and dynamics, as well as galaxy UV luminosity function.
