Research interests:

My research is centered on gaining a greater understanding of how microbial diversity is structured at several different levels; that is, how genetic and ecological factors affect communities, species, and populations, and how they respond as environments change. I have studied the effects of changing environments in the context of the microbiology of energy issues. My areas of energy-related research include 1) Microbially influenced corrosion (MIC, biocorrosion) and biodeterioration of petroleum products and biofuels, 2) Molecular characterization of microbial isolates and enrichments capable of anaerobic biodegradation of hydrocarbons, 3) Bioremediation of soil ecosystems contaminated by oil and oil-field brine, and 4) Microbially enhanced oil recovery (MEOR).

Another branch of my research focuses on the genus Bacillus, including studies of gene transfer within and between species, determining levels of genetic variation within populations, and systematics. The genus Bacillus, with many culturable members, offers an outstanding opportunity for research in microbial systematics and evolution, as well as offering strains for use in MEOR.
My research draws on many different areas of microbiology as I use the tools of molecular biology to characterize microbial communities and species. I enjoy the challenge of multidisciplinary collaborations with scientists and engineers striving to solve complex real-world problems.
