Research Interests

My research is highly interdisciplinary and has both a geomicrobiology and applied microbiology focus. I use molecular, physiological, microscopic, and bioinformatic techniques to understand how microbes respond to environmental conditions and in turn how microbes can modify their environment. For example, temperature, pH, and salinity control microbial distributions; however, microbial processes affect biogeochemical cycles both at the local and global scale. Elucidating the interdependence between microbial and geologic processes is needed to understand global functioning and response to climate change, potential clean up of contaminated environments, and limits to life. The geomicrobiology side of my research, specifically, has addressed the questions: How does environmental stress alter microbial distributions and functions, and what microbial attributes affect biogeochemical cycles? In general I ask these questions in extreme environments that have an abundance of novel microorganisms and functional pathways; yet often provide a simplified view of the microbial ecology that can provide insight into more complex environments, life on early Earth, or potential life on other planets. Some of the environments that I have studied are deep marine sediments, terrestrial hot springs, and Tibetan saline lakes.

The applied side of my lab uses a systems biology approach to modify microbe-microbe and microbe-environment interactions for the benefit of humans. Currently, I am working on increasing the efficiency of producing bio-products. Olefins such as ethylene, propylene, and isobutene are hydrocarbons that are key precursors for numerous chemicals and are currently primarily produced through petrochemical processes. Bioproduction of these olefins may replace petrochemical production given key advances in both fermentation reactions and optimized microbial interactions. For example, in manure microbial communities work together to ferment organic carbon into methane. However, a significant amount of chemical energy remains even after methane is produced. More efficient reactions that produce industrially significant hydrocarbons are needed.
