We all co-exist with bacteria and share our body with trillions of microbes. Human microbiome has been established to be evolved in a growing list of disorders and diseases such as cancer, enteric infectious diseases, aging, obesity, diabetes and neurological disorders. In my group, several projects about microbiome are ongoing with a focus on shaping vaginal microbiota balance and addressing the relations between microbes and infections. Microbes and host reactions including immunity responses are also under investigation. By joining the projects, students will be able to learn bacteria culture, microbiome extraction, sequencing, bioinformatic analysis, infection tests, cell culture and immunity analysis such as Fluorescence-activated cell sorting (FACS).
