Kushan’s current research is focused in plant responses to environmental change, especially native flora in degraded habitats and those co-occurring with invasive Acacias. He is also involved with developing propagation and agronomic practices of selected native species for urban gardening and studying the silviculture of economically important trees such as Sandalwood (Santalum spp.) and Agarwood (Aquilaria spp.).

Kushan has received numerous professional awards during his academic career. These include the University of Peradeniya Scholarship awarded for achieving best results in Bachelor of Science Hons. Degree, and International Postgraduate Research Scholarship (IPRS) from the University of Western Australia for his doctoral studies. As a mid- career researcher, he was awarded the J. William Fulbright Senior Fellowship, USA to pursue advanced research in the areas of plant ecophysiology. He was a recipient of the Third World Academy of Science (TWAS- Trieste, Italy) Young Scientist Award for Biology. This is awarded to recognise and support outstanding achievements made by mid-career Biologists from developing countries whose research work has significantly contributed to the advancement of sciences. Prior to joining FedUni, Kushan has served as an associate professor at the University of Brunei Darussalam and  adjunct associate professor at the Old Dominion University, Virginia, USA.
