Dr. Sushim Gupta

My research has been multidisciplinary from plant genetic engineering to genomics that enabled me to look for the solutions with different perspectives. I obtained my PhD in Biotechnology from National Chemical Laboratory, India on plant genetic engineering. As I began my postdoctoral tenure my research switched to clinical microbiology. I worked on phenotypic and genotypic characterization of multidrug-resistant pathogenic microbes and assessed bacterial genomics to decipher the molecular mechanism of antibiotic resistance. Thereafter, I worked on foodborne pathogenic bacteria and explored the metagenomics and genomic data to identify molecular mechanisms of resistance corroborating with resistance phenotype, identification and molecular characterization of vehicles of dissemination of resistance genes, virulence, and phylogeny. Currently, I am working on the characterization of multidrug-resistant Staphylococcus aureus mutant strains that leads to reduced ethanol susceptibility and determining the genetic variations associated in Vancomycin-intermediate Staphylococcus aureus (VISA) strains. I am also deciphering the resistance mechanism of emerging pathogen Elizabethkinigia, a vancomycin resistance Gram-negative bacteria in Dr. John Gustafson's lab at the Department of Biochemistry and Molecular Biology, OSU, Stillwater, OK.
