Research and Teaching Interests

Major area of research is on radiation processing. This work is carried out in collaboration with the Atomic Energy Authority of Sri Lanka. I am a member of the national research group on Radiation Processing (RAS/8/106). Present research is based on radiation processing of natural polymers. At present research work on radiation processing of chitin/chitosan is underway. Research work is being carried out to determine the potential of using irradiated chitosan as a natural antifungal agent against postharvest pathogens in banana. The ultimate goal of this research is to develop an antimicrobial food packaging film using irradiated chitosan.
