Assistant Research Fellow
PhD – University of Freiburg, Germany, 2007
Research Fields
Physiology and metabolism of bacteria, biodegradation and bioremediation, and microbial metabolomics
Major Research Achievements (2013-2017)
  • Metabolic diversity of anaerobes: Microorganisms maintain the biosphere by catalyzing biogeochemical processes, including carbon and nitrogen cycles. Anaerobic steroid catabolism by the denitrifying bacteria is relevant to both cycles. Although huge amounts of steroid compounds are produced and released to the environments by animals, fungi, and plants, to date almost nothing is known about how bacteria degrade steroid compounds in anoxic environments. Currently, we apply molecular and OMICs approaches to identify the intermediates, genes, and enzymes involved in anaerobic steroid catabolic pathways.
  • Allelochemicals produced by cyanobacteria: Bioactive compounds synthesized by freshwater and marine cyanobacteria have been studied in great details. However, much less is known about the bioactive secondary metabolites produced by terrestrial species. Metabolomic techniques are applied to search for antimicrobial compounds produced by cyanobateria inhabiting the surfaces of rock and bark, and soils.
Research Interests
  • Metabolic diversity of bacteria, especially anaerobes
  • Microbial metabolomics
  • Biodiversity of bacteria and algae
    Ongoing projects
    • Anaerobic metabolism of steroids by the denitrifying bacteria (NSC grant)
    • Aerobic metabolism of steroids by bacteria
    • Bioactive secondary metabolites produced by cyanobacteria
