ABOUT ME

CURRENT RESEARCH THEMES
My research has focused on development and implementation of high-throughput functional genomics to investigate genes involved in bacterial virulence and the biology of multidrug resistance plasmids. I am one of the original inventors of the transposon directed insertion-site sequencing (TraDIS) technique at the Wellcome Trust Sanger Institute, Cambridge, UK (Genome Research) and successfully transferred the methodology to the University of Queensland, Australia, establish it as the first in Australia capable of performing this innovative technology. I have applied TraDIS to study multiple pathogens, including Salmonella Typhi and Typhimurim, uropathogenic E. coli (UPEC), Klebsiella pneumoniae and Mycobacterium tuberculosis. In UPEC, I used TraDIS to to study multiple aspects of uropathogenic E. coli virulence, including serum resistance (PLoS Genetics), zinc resistance (PNAS), capsule regulation (MBio), polymixins resistance (JAC), cefotaxime resistance (JAC), and motility (PLoS One). A focus of my recent research has been the study of multidrug resistance plasmids. My works shed lights on the genetic requirement for plasmid replication and conjugation, including IncF plasmids (PloS One), IncC plasmids (Nature Microbiology) and I-complex plasmids (PLoS Genetics). Since 2017, my research has expanded to using next-generation sequencing to understand the population genetics of Vietnamese population (Human Mutation, Scientific reports), as well as cancer genomics (BMC cancer, Frontiers in Oncology, Bioinformatics).

isoniazid) and fluoroquinolones.
Thesis Title: Analysis of IncHI1 plasmids in Salmonella enterica serovar Typhi
- Set up Plasmid Multi-Locus Sequence Typing for IncHI1 plasmids
- Transposon Directed Illumina Sequencing (TraDIS - Transposon mutant library combined with Illumina sequencing) using 1.1 million mutant library to identify genetic elements contributing to the stability of IncHI1 plasmids in S. Typhi.
- Site-specific mutagenesis (using suicide vector) to generate knock-out mutants that de-stabilise IncHI1 plasmids.
- Used phenotype arrays and gene expression arrays to identify the effect of different IncHI1 plasmids on S. Typhi phenotypes and their global gene expression.
