Duleepa is a Research Fellow in the School of Public Health and Community Medicine, University of New South Wales. Duleepa graduated with a B.Sc. in Engineering (First Class – Honours) from the University of Moratuwa, Sri Lanka and recently completed his Ph.D. in Engineering (Bioinformatics) at The University of Melbourne. In his Ph.D. thesis, Duleepa developed novel statistical and combinatorial methods to uncover the genetic heterogeneity in viral metagenomes having clinical and ecological importance. His research interests are in the areas of applied statistics, combinatorial optimization and systems modelling. Duleepa is currently working on developing a novel methodology to combine evolution of B. pertussis genotypes with models of pertussis incidence and control through vaccination with James Wood.
