Research Interests

I am interested in the identification of uncultured Bacterial and Archaeal phyla and their contributions to the evolutionary history of microbial life on Earth. The study of microbial diversity, ecology, and evolution in the context of microbial community structure and function.Microbial speciation and genetic modes of adaptation. The co-evolution of microbial partnerships and symbiotic interactions. Microbiology in extreme terrestrial and extraterrestrial environments. Geochemical cycling and the role microorganisms play on a global scale.
