Research Interests

The Ouverney lab attempts to characterize the genetic diversity of bacteria in natural microbial communities by type and function. Over 99% of environmental microbes are believed to be uncultivable, hence we rely primarily on culture-independent molecular methods to gather information on the composition and role of mixed microbial communities. Some uncultivable bacteria found in environmental samples have genetic counterparts in humans (or is it vice-versa?), and some of those bacteria have been recently associated with human diseases. Our research aims to discover the natural source of human-associated uncultivable bacteria and to compare the function of those bacteria in their natural environment as well as in the human body. To study function of microbes, we combine in situ hybridization with micro-autoradiography (STARFISH) to measure the nutrients a particular bacterium is able to take up. By knowing what a bacterium requires to grow can be used in medicine to curtail the growth of pathogens.
