    Qualifications

    • PhD (Biology) 2008. Katholieke Universiteit Leuven (Catholic University of Leuven), Belgium. A four year PhD program in the department of Biology,  Laboratory of Comparative Endocrinology, where in the influence of Thyroid Hormones on embryonic development were studied using zebrafish as a teleost model. Predominantly, target gene knock-down by morpholinos, gene expressions using real-time quantitative PCR, hormone and deiodinase enzyme assays were used.
    • International training on “Food safety management, quality assurance systems and risk analysis” in Belgium, conducted by Ghent University, Belgium
    • International training on Environmental Impact Assessment (EIA), conducted by Central Environmental Authority, Sri Lanka. 2014
    • MSc Aquaculture 2004. Ghent University, Belgium (Great Distinction). This international masters program in Aquaculture was completed as the best student of the year, with a research titled “The influence of stress on thyroid hormone production and peripheral deiodination in the Nile tilapia (Oreochromis niloticus)”.
    • Diploma in Complementary studies in Aquaculture 2003. Ghent University, Belgium (Greatest Distinction). This international diploma program in Aquaculture was completed as the best student of the year 2002-2003. A compulsory one semester study was done in Wageningen University, The Netherlands
    • BSc Agriculture 1998. This four year degree was obtained with a second class upper division. Specialization was done in animal science and the thesis specialization in Aquaculture, titled  “The influence of major water sources on white-spot and yellow-head virus diseases outbreak in Shrimps”
