Research Interests

Our laboratory addresses the key issues related to public and environmental health. My expertise centers on studying ecology of antibiotic resistance traits and food-borne pathogens in the gut of mammals, birds, insects, and the environment.

Development of bacterial resistance to important classes of antibiotics and the resulting loss of drug effectiveness for antimicrobial therapies pose a serious public health threat. We primarily study the ecology of zoonotic and food-borne pathogens in agricultural, veterinary, and urban environments with special emphasis on antibiotic resistant strains of enterococci and Shiga-toxigenic Escherichia coli (O157 and non-O157). Using molecular genotyping and diagnostics, we aim to understand how insects serve as a reservoir and play a role in the transmission of pathogenic/antibiotic resistant strains within and outside cattle feedlots, swine, and poultry farms. Pest management recommendation based on our results will strengthen pre-harvest food safety strategies.

Considering the close physical contact between the companion animals, their owners, and veterinary personnel, we conduct research to better understand the ecology of multi-drug resistant strains of enterococci in the veterinary hospital environment and in the gut of healthy and sick small pet animals.

Leishmaniasis is recognized as a fatal zoonotic disease in many parts of the world and sand flies are the invertebrate vector for the Leishmania parasites. We are deciphering the role of the sand fly gut microbiome in the vector competence, which will potentially lead to paratransgenic manipulation of flies in order to curb the human outbreaks.

I am also interested in bacterial systematics including identification of novel taxa using polyphasic taxonomic approach. Responsibilities other than research involve lab management, grant preparation, scientific presentations, training and supervising undergraduate and graduate students and visiting scholars.
