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.
