Main
emphasis of current research is in the applied environmental microbiology,
microbial ecology and microbial physiology of microorganisms that respond
to or affect environmental health or ecosystem function. I have also initiated
a project “Phytopathogens as Agents of Bioterrorism” that
will develop methods for the detection and risk assessment of introduced
phytopathogenic microorganisms on food and fiber production. Other interests
include: hydrocarbon biodegradation; includes the environmental effects
of both hydrocarbon pollution and of remediation efforts on polluted sites.
Biosurfactants produced by microorganisms facilitate biodegradation of
hydrocarbons; I am interested in the genetic and physiological regulation
of biosurfactants production by bacteria, their toxicity relative to synthetic
surfactants, and their utility in remediation of hydrophobic spills (four
Master’s students). These research activities have components in
analytical chemistry, molecular biology, microbial physiology, and environmental
toxicology. I have a strong interest in environmental water quality, particularly
regarding microbiological, nutrients, and hydrocarbon contamination.
