Degrees:

Doctorate Agricultural Sciences
I studied the functional involvement of the group II HKT gene family in salinity tolerance of wheat for my PhD. Dr. Michael Francki, (Department of Agriculture and Food, Western Australia), and Prof. Tim Colmer (University of Western Australia) supervised my thesis. Title of the thesis was "Characterization of group II HKT gene families in bread wheat and their role in regulation of tissue Na+ and K+ under saline conditions"
2007
Master Agricultural Sciences
I studied association of phytoplasmas in sugarcane white leaf, brinjal little leaf, chilli narrow leaf and sesame phyllody diseases for my M.Phil. The study was a pioneering work in phytoplasmas diseases in Sri Lanka. Prof. E.H. Karunanayake (University of Colombo) and Mr. J.M.D.T. Everard (Coconut Research Institute of Sri Lanka) supervised my thesis. Title of the thesis was "Phytoplasmas diseases in crops with special reference to sugarcane phytoplasmas diseases in Sri Lanka"
2008: Post graduate course on Applied Statistics (Biostatistics)
Postgraduate Institute of Agriculture, University of Peradeniya, Sri Lanka
2001
Undergraduate Biological Systems and Organisms
I specialized in Botany while Chemistry and Physics was studied as subsidiary subjects. I did my final year project on seed biology of a tropical fringe species with Prof. Nimal Gunatilleke and Prof. Savithri Gunatilleke. The project title was "Preliminary Investigation of seed dormancy in Coscinium fenestratum (Clobber.) Menispermaceae"
