I use high-throughput sequencing, bacterial genetics, and physiology to examine microbial responses to environmental inputs. Current projects in my lab include analysis of bacterial communities in and on weathering concrete, visualization of rhodopsins in aquatic environments, light-sensing by heterotrophic Actinobacteria, and phosphorus acquisition in in an oligotrophic ferruginous tropical lake.
