I use high-throughput sequencing, bacterial genetics, and physiology to examine microbial responses to environmental inputs. Current projects in my lab include microbial signaling in coastal and hot spring biofilms, the effects of chemical amendments on carbon fixation rates and gene expression in a ferruginous tropical lake, and preliminary analysis of the microbial communities in oil sands waste.
I am currently looking for 1-2 graduate students. Please contact me if you are interested in any of these projects.
