Research. Molecular Biology of Bacterial Antibiotic Resistance Genes and degradation and toxicity of organic chemicals.

Satish K. Walia studies molecular mechanisms of antibiotic resistance in bacteria and biodegradation of xenobiotics such as polychlorinated biphenyl,nitrotoluenes, and the mutagenic properties of their biodegradation products. He has developed gene probes to monitorexpression of catabolic genes during in-situ bioremediation of polycyclic aromatic hydrocarbons, gasoline, and PCBs.

Recently, his laboratory discovered emergence of infectious multiple antibiotic resistant bacteria Vancomycin resistant in amphibian feces, farm soil and urban backyard soil. Studies on the prevalence and the mechanism of resistance are in progress. He has authored over 50 papers and presented his research at national and international symposia and meetings . His research has been supported by the Environmental Protection Agency, General Motors, and local area hospitals. Several students at the doctoral, masters, and undergraduate levels have participated in his research and have co-authored publications. In recognition of his contributions to the profession of microbiology, he is an elected Fellow of the American Academy of Microbiology.
