Research

I am interested in plant taxonomy, systematics and ethnobotany. Former projects involved ‘Systematics and Biology of New Guinea Begonia’ and ‘Ethobotany and plant diversity’ - incorporating folk knowledge with plant use in New Guinea communities.

My current research focuses on the systematics and evolution of the genus Elaeocarpus L. (Elaeocarpaceae) focussing on New Guinea species. This study aims to utilise molecular phylogenetics and fruit morphology of both extant and fossil material to investigate the evolution of the genus, including dating of past events. Specifically, I aim to: 1) reconstruct the phylogeny with a focus on species from New Guinea which are currently under-represented in existing data sets, 2) determine the evolutionary patterns of fruit morphology in the genus, 3) resolve the phylogenetic placement of fossil Elaeocarpus fruits and 4) use these fossils to calibrate the molecular evolutionary rate and thereby determine the dates of evolutionary events within Elaeocarpus. The results of my research will provide further insights into the evolutionary history of Old World tropical forests.
