Impacts of invasive animals on ecosystemsBiodiversityWater quality and aquatic insect communitiesTiger beetlesFreshwater aquatic insects
I teach and research at the Department of Zoology and Environment Science, Faculty of Science, University of Colombo, Sri Lanka. I am currently working on the water quality and aquatic insect communities from streams and rivers of Sri Lanka (supervising a postgraduate student) and on interactions of insect fauna with invasive alien plants, and on butterfly diversity and community changes in a wet zone high biodiversity area in Sri and Lanka (both undergraduate research projects). I am continuing work and publishing the findings of a nearly ten year long survey of tiger beetles of Sri Lanka while being co-supervisor of a postgraduate student on this topic. With aquatic insects and with tiger beetles I am exploring along with my co-workers the possibility of using aquatic insects and tiger beetles as indicators of habitat quality in Sri Lanka. I serve on numerous committees both national and sectoral on biodiversity, alien invasive animal species, insect vectors of diseases such as Dengue, Chikungunya etc., and on threatened insects of the country.
