Current projects in the lab include:
- Examining how microbial communities assemble and change over primary succesional sequences, including recently deglaciated ecosystems.
- Looking at the relationship between carbon cycling and microbial community composition in tropical forests.
- Examining the links between humic acids, redox conditions, and microbial community composition in controlling arsenic cycling in Bangladesh Aquifers.
- Investigating the structure and function of microbial mats in the perennial streams of the McMurdo Dry Valleys, Antarctica.
- Incorporating phylogenetic approaches into traditional ecological techniques to compare and contrast microbial community structure across environments.
- Examining integron diversity and the effects of integrons on the shaping of microbial genomes.
