Research Overview

Biofilms are microbial communities with city-like structures and functions, enabling them to play complex roles in diseases and environment. We study, manage and control microbial biofilms in these situations: [1] biofilm interactions with host and environment; [2] development of biofilm control strategies; and [3] biofilm engineering in resource recovery and bioremediation.
