Research Interests

My work deals with the systematics, evolution and historical biogeography of tropical flowering plants with current taxonomic focus on Annonaceae, Begoniaceae, and Lauraceae. I am interested in the use of dated phylogenies, fossils, palaeogeographic reconstructions and various other disparate data sources to investigate the historical assembly of tropical floras, and the impact of historical processes on current patterns of species distributions and diversity in the Southeast Asian tropics. I dedicate substantial time to field and taxonomic work underpinning this research.


Current Research

1) Plastome phylogenetics and historical biogeography of Annonaceae subfamily Malmeoideae.

2) Historical biogeography of Goniothalamus (Annonaceae).

3) Plastome phylogenetics and historical biogeography of Asian Lauraceae.

4) Revisionary work on Alseodaphne, Dehaasia and Nothaphoebe (Lauraceae) for the Flora Peninsula Malaysia and Flora of Singapore.

5) Systematics of Southeast Asian Begonia.
