Dr. Thushan Ekneligoda has more than 20 years of experience in teaching geotechnical and structural engineering, he has an extensive experience in numerically modelling underground coal gassifiction and geothermal sites. Dr Thushan completed his first post-doctoral research fellowship in Seoul Nationla University South Korea. During that period he carried out an extensive study of extraction of geothermal energy. Then he joined the university of Nottingham. He spent two years in Nottingham. In addition to his main research he carried out teaching for the 1st and 3rd year students.

In addition to his academic contributions he worked as a consultant engineer for two years in Itasca Gomechanic in Sweden. He carried out modelling of nuclear waste disposal sites, underground mining sites, many models related to slope stability during this period. Dr Thushan completed his PhD at Royal institute of technology in Sweden. He read his MSc also in the same university.
