Research Interests

The main theme of my research is to develop novel antimicrobial agents which have the potential to be used as natural food preservatives, animal feed additives or novel antibiotics against drug-resistant bacterial pathogens. We use natural antimicrobials such as bacteriophage, bacteriocin, and essential oil compounds to enhance food safety. My other research primarily focuses on developing novel peptide and lipopeptides as new drug candidates for the treatment of bacterial infections caused by antibiotic-resistant bacterial pathogens. I contributed to the discovery and development of several novel antimicrobial agents, particularly paenibacterin (lipopeptide) and paenipeptin (lipopeptide). These novel antimicrobial compounds show potent activity against antibiotic-resistant pathogens. After the discovery of these antimicrobials, we determined their mechanisms of action, toxicity, biosynthesis, and therapeutic efficacy in animal models.
