Lecturer (Probationary)
Address: Department of Zoology

I have broad research interests on animal behaviour, evolutionary ecology and insect-plant interactions. Particularly I am interested in evolution of animal mating strategies in terrestrial arthropods. I am currently reading my Ph.D. degree at Macquarie University, Sydney, Australia and my current research focuses on evolution of male mating strategies in response to sexual selection and sexual cannibalism in a praying mantid mating system. I completed my B.Sc. (Zoology special) degree in the University of Peradeniya, Sri Lanka with a first class honours in 2010 and worked as a temporary academic staff member of the department from 2010 to 2013.
