Research Interests: 

My research interest is in the area of value-added food processing by utilization of emerging food processing and packaging techniques. I am especially interested in the development, characterization, and application of biodegradable and edible packaging materials, and use of edible coating, vacuum impregnation, and infusion technique for developing high quality, longer shelf-life, and value-added fruit and vegetable products. I am also interested in the quantification of bioactive compounds and antioxidant capacity of small fruit and fruit products associated with post-harvest storage and processing.
