Research Interests

Waterborne fecal contamination is associated with human health risk. Monitoring and source identification of fecal contamination in tropical environments pose a great challenge as fecal indicator bacteria developed and applied in temperate climates have been associated with environmental growth in the tropics. Tropical urban environments pose a greater challenge due to the presence of multiple potential sources of fecal microbial pollution.

My research is applying molecular biology tools (qPCR, digital PCR, & next generation sequencing) to contribute to addressing these challenges. I am interested in understanding:
1.How do bacterial communities and subgroups of sewage-associated taxa and pathogen-like bacteria vary as a function of land use, sites, and water quality in tropical urban     catchments?
2.Can 16S rRNA host-associated Bacteroidales assays be used to effectively identify and distinguish non-point sources of fecal microbial pollution in urban tropical environments?
3.What indicators are appropriate for tracing pathogens from sewage contamination in tropical sediment-rich environments? Are sediments a reservoir, and potential source of fecal microbial pollution?
