Research Interests


I have been working on the antibiotic resistance mechanism and the cell membrane transporter in Pseudomonas aeruginosa and Enterobacter cloacae for eight years. Currently we are focusing on the following studies: 1) Investigating the presence of disinfectant resistant bacteria in clinical settings;2) Analyzing resistance genes in antibiotic resistant Enteric bacteria; 3) Examining the accumulation/efflux of antibiotic in the bacteri
