About
My primary vision is to assist the biodiversity conservation of Sri Lanka by developing the necessary knowledge and creating awareness among people, especially among students.
Thus, my major research interest is to study the seed biology of ecologically and economically important native species. I have identified traditional crops, crop wild relatives, species in IUCN threatened categories and medicinal plants as economically and ecologically significant species that needed our attention. These species have to be conserved to gain their ecological and economic services continually. Thus, I study the seed biology of these species assisting their in-situ and ex-situ conservation. Some of my studies focused on developing environmentally friendly methods to improve the seed quality of traditional crop species. Moreover, research on medicinal plants not only focused on developing propagation protocols but also on developing their plant architecture to use them as ornamental species. Thus, these species will have a demand as ornamental plants and thus, will be popular among people, ensuring their conservation.
I developed my career through the skills and knowledge I obtained especially during my B.Sc. and Ph.D. studies. I completed my B.Sc. degree with a first-class honours degree from the Department of Botany, University of Peradeniya, Sri Lanka. during my undergraduate degree, I was fortunate to get an opportunity to work on seed biology of Sri Lankan dry zone forest species which develop my interest in seed biology. I was fortunate also to secure a position at the University of Kentucky, USA to do my Ph.D. under the mentorship of two world-renowned seed biologists, Profs. Jerry and Carol Baskins. Through the Ph.D. study, I polished up my skills in seed biology which allowed me to develop seed biology research in Sri Lanka.
Currently, I am serving as a Professor in Botany in the Department of Botany, University of Peradeniya, Sri Lanka. I bare the responsibilities of teaching undergraduate courses in B.Sc. degree programmes offered by the Faculty of Science. Further, I have to conduct research and participate in faculty administrative activities. Thus, currently, I am the Head of the Department of Botany administrating the academic work of the Department.
Further, I also worked as a visiting lecturer at the Postgraduate Institute of Science (PGIS), University of Peradeniya, the postgraduate arm of the Faculty of Science. In the PGIS, I am involved in teaching M.Sc. programmes and mentoring M.Sc. M.Phil. and Ph.D. students in their research projects. Up to now, I have mentored three Ph.D. students and > 20 M.Sc. students. Currently, there are one Ph.D. and one M.Phil. student working in my laboratory.
As my national contribution, I worked on various committees including the National Experts Committee on Mangrove Biodiversity Conservation. Further, I provide my expertise on various National level projects in biodiversity conservation.
