Fields of academic interests

Research interests:

  • Microbial diversity and environmental microbiology of extreme ecosystems (e.g. mine water, sub-soil brine, highly saline soil and water).
  • Protozoan and bacterial expression analysis of metal resistance key genes (e.g. cop, cnr, mer, chr, czc, ncc).
  • Analyses of key genes (cbbL, nifH, amoA, apsA, dsrAB) involved in biogeochemical cycling of nutrients and their role in Enhanced Biological Phosphate Removal process (EBPR).
  • Biotechnology: Bioremediation- inorganic pollutants, persistant organic pollutants and emerging organic pollutants.
  • Functional metagenomic analyses.
  • Microbial enzyme production, organic degradation pathway.
  • Enteropathogenic microbes in both water and food, and their related public health concerns.
