OverviewAI-generated summary

Ohgew Kweon's research focuses on the microbiological and molecular characterization of bacterial contamination and resistance mechanisms. His work includes investigating microbial contamination in commercial tattoo and permanent makeup inks, with follow-up studies examining the prevalence of such contamination in products marketed in the United States. Kweon also studies the adaptive responses of bacteria to antimicrobial agents, including investigations into resistance to extended-spectrum cephalosporins in clinical isolates and the global proteome response of bacterial biofilms to subinhibitory concentrations of antibiotics. His research employs techniques such as droplet digital PCR and loop-mediated isothermal amplification for the detection of specific bacterial complexes in various samples, including pharmaceutical products and antiseptics. Kweon has published 38 papers, accumulating 324 citations and an h-index of 9. He has collaborated extensively with Seong‐Jae Kim, Steven L. Foley, Saeed Khan, and Kidon Sung, all from the National Center for Toxicological Research, with whom he shares multiple publications.
