RESEARCH FOCUS

  • Research area: Food safety and risk assessment
  • Key words: Food safety risk analysis, quantitative microbial risk assessment, predictive microbiology, food safety engineering, and molecular epidemiology
  • Research aims at integrating experimental and field data with mathematical modeling, and developing predictive and risk assessment models that will aid in guiding several stakeholders such as policy makers, government agencies, consumers, and food industry to improve food safety and public health
  • Conduct interdisciplinary research to address critical food safety issues related to foodborne pathogens (e.g., Escherichia coli, Salmonella, Listeria monocytogenes, Toxoplasma gondii) in different food categories such as fresh produce, meat and poultry, dairy, and low moisture foods: pet foods and chocolate
  • Recent research projects include predictive modeling and quantitative risk assessments for pathogenic bacteria and parasite Toxoplasma gondii in produce, meat, and dairy products; antimicrobial resistance and dynamics of endemic infectious diseases on dairy farms
  • In addition, currently exploring appropriate methods and approaches to integrate molecular data (e.g., whole genome sequencing) and risk models to evaluate public health risk
