Areas of Interest

I am interested in microbial speciation and genetic modes of adaptation. 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. 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.

Research

Bacteria and archaea live in nearly all environments on Earth, even under what we consider to be some of the most extreme conditions imaginable. The phyla of Eukarya, which include all plant and animal life, compose the least genetically diverse evolutionary branch. In contrast, the unseen world of Bacteria and Archaea represent the overwhelming majority of biological diversity on Earth, and most have yet to be identified or cultured. In all environments microbial diversity organizes into complex ecosystems – populations working together and competing amongst each other for survival. Only recently has it become technologically possible to sequence entire communities and to study the structure and function of these microbial communities in their natural state. Examining how microorganisms evolve and metabolize in their environment is important to understanding our world, and has been the major focus of my research over the past five years at 海角社区. To answer these questions, I study a broad range of interesting environments ranging from hot springs, the deep subsurface of the Earth, oceans and soils.
