Investigating the Effect of age of mice on the systemic immune response to oro-nasal immunizations with Plasmodium falciparum antigen 2 expressed on cell walls of Lactococcus lactis and investigating the gross anatomical, histological and pathological changes in mucosal associated lymphoid tissue.

Normal morphological and morphometric studies of mitral and aortic valve in a Sri Lankan population.

Incidence of Antisperm Antibodies (ASA) and its association to subfertility in couples undergoing Assisted Reproductive Technologies at a selected centre.

An anatomical study of human skeletal remains from the excavation site in Bellanbadipalassa in Sabaragamuwa Province, Sri Lanka.
