I am interested in the systematics, evolution and historical biogeography of the Australasian flora. For my PhD I studied the systematics of Loganieae, an Australasian-Pacific tribe of Loganiaceae (Gentianales), focusing on Mitrasacme and the related genera Adelphacme, Phyllangium and Schizacme. Mitrasacme predominantly occurs in the Australian Monsoon Tropics. In contrast, Schizacme occurs in montane habitats in south-eastern Australia and New Zealand.
My current project on Spermacoceae (Rubiaceae, Gentianales) further develops my interest in the Australian Monsoon Tropics flora. Within Spermacoceae, multiple lineages with floristic links to the Americas, Asia, Malesia, and the Pacific now form part of the monsoonal biome.
