My interdisciplinary research combines computational biology, genomics, high-throughput and targeted mutant generation, and biochemical and molecular methods to determine the genetic requirements for microbial functions of interest. I use genomics to determine how a microbe adapts to survive and at times even thrives in an environment. I am particularly interested in the community structure and function of anaerobic microbes when attached to surfaces as biofilms because on or near a surface tends to be where the most active (and interesting IMO) microbes are often found.
