My graduate research focused two areas under the broader scope of anaerobic microbiology and microbial ecology. First, I identified and characterized denitrifying bacteria that are involved in bioremediation of an acidic high-nitrate and uranium-contaminated aquifer. Second, using public 16S rRNA gene-based surveys, I described the ecological distribution of novel and uncultured clades within the two bacterial phyla Proteobacteria and Fibrobacteres.
During my postdoctoral career, I analyzed large environmental RNA datasets (metatranscriptomes) obtained from a unique sulfur cycling spring, called Zodletone Microbial Observatory determining functions of novel microbial groups and identifying microbial lineages involved in various sulfur cycling pathways. This has led to my current research, where I hope to use the information gathered from these large datasets to isolate and characterize novel microorganisms involved in sulfur transformations.
I currently have an active undergraduate research laboratory in anaerobic microbiology and microbial ecology. Please contact me if you are interested in performing an independent research project in one of these areas.
