Dr Hammer is currently a Postdoctoral Research Fellow at the University of Adelaide and the State Herbarium of South Australia, a position funded by the Australian Biological Resource Study’s National Taxonomy Grant Program. Tim’s current project is to write a revisionary taxonomic synthesis for the genus Hibbertia (Dilleniaceae) within Australia and to conduct studies into its biogeography, evolution and phylogenetics. In this role, I am writing the Flora of Australia treatment for the family Dilleniaceae (>300 species). I received my PhD from The University of Western Australia (Australia) in 2019, completing my doctoral thesis on the taxonomy and evolution of the Australian plant genus Ptilotus (Amaranthacea).
