Research interests:
  • Soil microbial community structure
  • Soil environment-microbe interactions

In the Hallam laboratory I focus on using metagenome analysis, a method that involves simultaneously characterizing the DNA from millions of soil microbes, to study soil microbial communities from across the continent. The goal is to differentiate and compare the genetic potential of microbes found in several North American ecosystems that are both undisturbed and disturbed (organic layer removal and/ or clear-cut). These results will not only be used to answer microbial ecology questions concerning ecosystem specific influences on the microbial gene pool, but will also be used to identify microbes that produce novel proteins or enzymes. Additionally, using metatranscriptome analysis, I hope to gain insight into the activities and metabolic functions performed by the microbial communities at the time of sampling.
