The microbiome comprises of all the microbial genetic material within an ecosystem or within special ecological communities. The human body contains over 10 times more microbial cells than human cells. We have just begun to appreciate the impact of microbiota (all microbes in a niche) on diseases like cancers, diabetes, schizophrenia and others. At the RGCB microbiome laboratory, we will study how imbalance in microbiota (particularly bacteria and viruses) can lead to acute (eg. diarrhea) and chronic (eg. cancer) diseases as well as altered nutritional statuses (eg. malnutrition) by metagenomic analyses using next-generation sequencing and other molecular methods.
