Dr Gillian KHEW Su-Wen




Research Interests

My research interests encompass the application of molecular biology to species identification, understanding evolutionary relationships and conservation. My work spans numerous plant families, extending into the fungal kingdom.


Current Research

  1. Molecular phylogenetics of Gesneriaceae, Dipterocarpaceae, Urticaceae, Cactaceae, Zingiberales, etc.
  2. Conservations genetics of Zingiberales and Hanguanaceae.
  3. Phylogenomics of the Flora of Singapore.
