We use interdisciplinary approaches including molecular genetics, biochemistry, cell biology, and structural biology to understand the pathogenesis of opportunistic Gram-negative bacteria at molecular and cellular levels. Burkholderia, Achromobacter, and Enterobacter species are the main model organisms we use in different aspects of our research program.

Current interests are: (i) To advance the understanding of the assembly and modifications of lipopolysaccharide (LPS) and glycosylation of envelope proteins; (ii) To elucidate the molecular basis of intrinsic multidrug antibiotic resistance in resilient opportunities Gram-negative pathogens; and (iii) to exploit our finding to develop novel means to combat antibiotic resistant pathogens.

I carry out hypothesis-driven research and train pre and postgraduate students and postdoctoral fellows to become outstanding biomedical scientists, to develop an environment of scientific inquiry and respect for each individual's expertise and contribution, as well as emphasising personal and scientific integrity and team player skills.

Hypothesis-driven research on:

  • Molecular mechanisms of intrinsic multi-drug antibiotic resistance
  • Biogenesis of the Gram-negative bacterial outer membrane, especially lipopolysaccharide and cell wall peptidoglycan
  • Cellular microbiology of opportunistic  Gram-negative bacterial pathogens in phagocytic cells.
