My research focus is on protein or biopolymer materials, including fibrous proteins (silks, elastins, resilins, keratins, collagens), variable plant proteins (zeins, soy proteins, etc.) and other recombinant or natural polymers, and their related engineering technologies to control the self-assembly of these polymer systems into functional materials. These materials can be fabricated into tunable forms such as films, gels, particles, fibers, or composites, and can be widely used for different green or biomedical technologies, including tissue regeneration medicine, disease model, controlled drug delivery and release, antibody and vaccine storage, flexible biosensors, green plastics, biophotonics, and nano-biotechnology.
