Research

The Food and Biomaterials Engineering Lab aims to address critical challenges related to the microbe-material interface within agricultural and food systems. We are using a combination of multidisciplinary approaches encompassing food process engineering, material science, mathematical modeling, microbiology, molecular imaging, and high-speed photography to answer key scientific questions. The primary research areas are:

  • Novel food processing for improving food safety and security
  • Bio-based delivery systems utilizing food by-products and waste
  • Functional materials for enhancing food safety and reducing food loss
  • AI-enabled food system design for high-efficiency production

Biobased Target Delivery Systems

Innovations in bio-based delivery systems can address critical challenges in food safety and sustainability. By harnessing the intrinsic properties of bio-based carriers, these targeted delivery systems can stabilize the encapsulated chemicals/microbes and improve the binding affinity of biocarriers, leading to enhanced inactivation of pathogenic and spoilage microbes on food and food contact surfaces. This can reduce the reliance on conventional synthetic sanitizers and potentially decrease water and energy consumption. Furthermore, these bio-based microcarriers can serve as targeted delivery systems for bioactives, promoting human health.

Functional Materials and Interfaces

Our group is devoted to exploring cutting-edge materials, such as coatings, hydrogels, and 3D scaffolds, to address significant challenges at the microbe-material interface across diverse food and agricultural applications. One of our core pursuits involves developing versatile, surface-independent, antimicrobial and antifouling coatings. These strategies can mitigate cross-contamination risks from food contact surfaces, thereby curtailing the spread of pathogenic and spoilage microbes across successive food batches. Another area of interest is unearthing biobased materials and scaffolds that promote the colonization, growth, and metabolic activity of microbes, even under severe environmental conditions.

AI-Enabled Food System Designs

Many existing food system designs draw from established practices, leading to notable food safety concerns and significant waste/loss. Our research aims to create a rapid-response platform utilizing cost-effective, food-grade materials that integrate autonomous sampling and detecting functions. We will also introduce innovative decision-support tools to enhance food traceability and sustainability. This integrated approach is designed to boost production efficiency and preemptively address biological and chemical risks throughout the whole food supply chain.
