ABOUT ME

Assoc Prof. Kushan specializes in plant functional & developmental biology, physiology and biology of native flora. He obtained BSc First Class (Hons.) degree from University of Peradeniya in 1992. In 1997, he completed his PhD at University of Western Australia in South West Australian native flora.
He 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 (1992), and Overseas Postgraduate Research Scholarship (OPRS) from the University of Western Australia (1993) for his doctoral studies. In 2005, he was awarded the J. William Fulbright Senior Fellowship, USA to pursue advanced research in the areas of plant developmental biology and ecophysiology. Assoc Prof. Kushan was a recipient of the Third World Academy of Science (TWAS) Young Scientist Award for Biology. This is awarded to recognize and support outstanding achievements made by mid-career Biologists from developing countries whose research work has significantly contributed to the advancement of sciences. In 2006 he received a Fulbright Occasional Lecturer award to deliver a lecture at the University of Mississippi, National Center for Natural Products Research, USA. He was a recipient of Sri Lanka Presidential Awards for Scientific Research for three consecutive years. Assoc. Prof. Kushan has served as an adjunct associate professor at the Old Dominion University, Virgina, USA. He was the program leader of the Environmental and Life Sciences Program of Faculty of Science in 2010. Currently he is serving as the Director, Institute for Biodiversity & Environmental Research (IBER) of UBD.
