Microbes live mostly in communities with other microbes in nature, including host-associated microbes, forming the different microbiota. In nature, most microbes are found living in microbial biofilms, rather than as free-living organisms. However, biofilms of human-associated microbes are usually linked to pathologies. I am focused on the study of commensal and/or host-health beneficial microbes' capacity to form biofilms within the host. Furthermore, I am interested in harnessing this capacity to impact host health and disease states, using microbial genetics and synthetic biology approaches.
