Research Interests            

Research in food microbiology and safety laboratory focuses on improving microbiological safety of foods including bacterial stress adaptive response, intervention and preservation technologies, and molecular based rapid detection methods.

1. Bacterial stress adaptive response

Our research focuses to elucidate how foodborne pathogens can survive in adverse environments with lipidomics, genomics and proteomics tools. This research also includes evaluating the survivability of foodborne pathogens adapted under various stress conditions in a simulated dynamic gastrointestinal model.

2. Intervention and preservation technologies for enhancing food safety

Our researches are conducted to develop, improve, and evaluate physical, chemical, and biological intervention technologies to enhance the quality and safety of foods.

3. Improvement of molecular-based detection of foodborne pathogen in foods

The rapid and accurate identification of bacterial pathogens from food samples is important, both for food quality assurance and to trace outbreaks of bacterial pathogens within the food supply. Therefore the purpose of this research is to develop or improve rapid detection tools using molecular and immunological methods. Our research projects also include developing appropriate microbiological media for the recovery of environmentally stressed or injured foodborne pathogens from foods to shorten enrichment time.
