Research interests

Microbial diversity and activity; linking microbial function and phylogeny

The goal of my research is to understand the role of microbial communities involved in biogeochemical cycling and other important transformations. My primary focus is on methanotrophic bacteria, which are microorganisms that use methane as a sole carbon and energy source. The activity of methanotrophs mitigates the release of methane to the atmosphere and therefore has an important role in controlling greenhouse gas levels. Methanotrophs are active in many environments, including lake sediments, wetlands and upland soils.

Stable isotope probing (SIP) of nucleic acids is a key method that we use in my research group. SIP helps us identify active microorganisms in environmental samples and allows us to capture their DNA and RNA. Combining SIP with ‘omics approaches (metagenomics, metranscriptomics, metaproteomics) can provide insights into the metabolic capabilities and activity of these organisms – many of which are still uncultivated and poorly characterized.

More recently, research in my group has turned to the belowground interaction between plants and microorganisms in the rhizosphere. We use cultivation, high-throughput sequencing and stable isotope probing to reveal associations and functions.
