My laboratory has two major areas of research within the field of microbial ecology. One of our objectives is identifying genetic determinants for adaptation to fluctuating environments. The other part of the lab focuses on studying microbial communities, the predominant species in desert conditions, and how they fluctuate upon availability of nutrients. Our approaches include genomic, proteomic, and molecular strategies to search for microbial adaptation traits and dissecting microbial communities.
