Other Teaching and Advising
In the past 5 years, I have mentored 10 undergraduate students and 2 high school science teachers in my research laboratory. I also served as the director of the NSF-REU: Bioprocess Engineering for Sustainability and the ICTAS-REU: Soft matter physics, from theory to application. Each year I mentor graduate students and student design teams. In the summer we have over 100 K-12 students in our laboratory to perform the Jell-O Plastics! hands-on lab. I am the faculty advisor for the Virginia Tech Student Chapter of the American Chemical Society Rubber Division.
Research in the Biopolymers and Bioinspiration Laboratory is focused on discovering new biopolymer structures and bioinspired polymeric materials and low energy processes to form them. Food Biopolymers like proteins and polysaccharides form networks with each other and the other molecules in the food like fats and flavor compounds. Food biopolymers need to be properly hydrated to yield good texture and flavor. Research focuses on biopolymer network formation and self-assembly, hydration level, and varying the hydrating molecules like water and sugars and how these factors influence food texture. Bioinspiration allows us to adapt natural phenomena to engineering practice. Flowers open and close and plant stems twist and curl to allow the plant to grow and thrive. Research focuses on extruding and molding synthetic polymer systems that can also open and close and twist and curl just like their natural counterparts and describing the material mechanics that govern such complex shape change. Research also focuses on understanding how environmental processes like water transport, sunlight, temperature, and impact allow plastic litter to breakdown to small microplastics (MPs) and become nuisances in the environment.
The Renewable Materials Research Group is part of the Biomolecular Engineering Cluster at Virginia Tech, which includes the Biofuels and Carbohydrates Laboratory , Metabolic Engineering and Systems Biology Laboratory , Ruder Research Group , and Zhang Research Group .
