  • Developmental and functional plant morphology
  • Evolutionary plant reproductive biology
  • Historical biogeography of flowering plants

Current Research 

  • Key functional floral traits in the early-divergent angiosperm family Annonaceae: gynoecial diversity and the evolution of strategies that promote pollination efficiency and pollen competition
  • Population genetics and conservation biology of the endangered tree Aquilaria sinensis in Hong Kong
  • Reproductive ecology and biogeography of Artabotrys (Annonaceae): using phylogenies to test hypotheses in plant-pollinator coevolution, pollinator trapping, and spatio-temporal changes in distribution ranges and ecological niches
  • Assessing key evolutionary innovations and founder events as drivers of speciation: an integrated phylogenetic approach to the study of evolutionary diversification in the genus Meiogyne (Annonaceae)
  • Pollinator trapping in the early-divergent flowering plant family Annonaceae: evolution of a mechanism that maximizes the efficiency of pollinator use
  • Pollination ecology, seed dispersal, population genetics and conservation biology of Thismia species (Thismiaceae)
  • Perianth evolution in the Annonaceae, an early-divergent family of flowering plants: integrating floral development, comparative transcriptomics and pollination ecology

Research Team

Currently one postdoctoral fellow (Dr GUO Xing), four PhD students (Mr CHEN Junhao, Mr LIU Ming Fai, Mr KWOK Wan Hin, and Ms CHEN Yanwen), and one MPhil student (Ms Ashini DIAS).
