She was also a National Research Foundation (NRF) fellow (2009-2014) and is now a NRF Investigator. She is a structural virologist specializing in x-ray crystallography and cryo-electron microscopy. Her research interest focus on the structural changes of flavivirus particles during its infection cycle and the effect of anti-viral therapeutics on them. She obtained her Msc and PhD in NUS and did her post-doctoral training in Purdue University under the supervision of Prof Michael Rossmann. Her laboratory made significant discoveries in the understanding of the structures of the Zika and dengue viruses, the morphological variants of dengue viruses, also how potent human antibodies neutralize flaviviruses and the structural changes of flavivirus during maturation.
