Specialised Research Area(s):
My current interests lie in the gene transcription of RNA viruses, with emphasis on influenza and coronaviruses. RNA viruses encode their RNA polymerases to replicate the viral genome. The error-prone transcription process of RNA polymerases is the main driving force for viral genetic diversity essential for adaption to and infection of the host. However, the accuracy of virus transcription must be maintained at a certain threshold for faithful gene expression and protein production. I am interested in understanding the structural basis of how viral polymerases regulate transcription accuracy in RNA viruses and the biological consequences of transcriptional errors during infection by developing a novel genomics platform and using Cryogenic Electron Microscopy (Cryo-EM). These fundamental insights are essential in the basic understanding of gene transcription and virus evolution and the biomedical research for the development of antiviral drugs and vaccines for infectious diseases.
