Welcome to the Laboratory for Microbial and Environmental Genomics (micro-omics). Invisible to the naked eye, microbes are the most abundant organisms on earth, yet the extent of their diversity and influence remains largely unknown. Our laboratory explores the distribution, diversity and evolution of microbes in aquatic ecosystems. In particular, we are interested in how ecosystem change (e.g., pollution, eutrophication, habitat loss and climate change) affects microbial populations. For this purpose, we frequently focus on bacteria belonging to the Vibrio genus, which contains many pathogenic variants (e.g. V. cholerae, V. vulnificus and V. parahaemolyticus). Current research addresses a variety of questions: does niche adaptation in the marine environment provide cross protection in the human host? what role do marine microbes play in the intrinsic biodegradation of plastic debris? how do anthropogenic stressors favor the evolution of antibiotic resistance in the natural environment? Research also includes microbial indicators of anthropogenic pollution (Escherichia coli and Enterococcus faecalis) and microbial pathogens of corals (Serratia marcescens).
