Research Interests:

I explore innovations in renewable energy generation and green retrofitting of industrial processes by engineering novel biological approaches to the reuse of waste products (i.e. carbon dioxide, wastewater). My research takes a bioprospecting approach, where I characterize communities of microbes from unique/extreme natural environments. From these communities, I isolate and culture individual strains and subsequently investigate their respective physiological and genetic traits. These microbes are targeted specifically for their metabolic capacities to consume or utilize CO2 in generating biofuels and other high value industrial compounds, either by natural or engineered pathways. My interests therefore lie most directly at the point where microbiology, genetic engineering and sustainable energy converge.

Furthermore, I am interested in how microbes affect the geochemistry of deep subsurface environments after injection of high pressure CO2 for long-term storage. To that end, I am researching the extent to which microbes catalyze biomineralization under high pressure CO2 conditions, a process that has the potential to reduce CO2 migration/leakage and improve the sealing capacity of reservoirs targeted for geologic carbon sequestration.
