Microbial life such as bacteria, fungi, and algae are integral to a naturally functioning aquatic ecosystem. By applying comprehensive molecular approaches, this laboratory is focused on characterizing the composition and distribution of microbial communities, and determining the functional roles as well as their interactions with environments.
