Research interests:
Microbial life represents the overwhelming majority of biological diversity on our planet. Most microbially-driven processes are polymicrobial, meaning that they are the function of complex assemblages of organisms that compete, coexist, and cooperate. My research uses powerful molecular tools and cultivation-based approaches to study microbial assemblages, novel microorganisms, and their roles in decomposition of organic substrates, corrosion of metal surfaces, degradation of hydrocarbon, production of biofuels, and the production of secondary metabolites.
