Research Interests

My overall research interests are sustainable food processing and safety engineering. Our mission is to improve the sustainability and safety of food production through applying processing and engineering knowledge and technology, and develop rapid detection and processing technology for detecting and controlling hazards unintentionally or intentionally added into food supply chain. The goal of our research is to provide valid solutions to improve our capability in food security and defense in addition to sustainability. Our group has also established a strong collaboration with food companies like PepsiCo Inc.  

  1. Organic Food Processing
  2. Food Safety Engineering
  3. Sustainable Food Processing via Byproduct Utilization
  4. Food Nanotechnology
  5. Rapid Detection of Hazards for Food Defense
  6. Food Security
