Dr Thilakarathna is a research fellow at the Department of Infrastructure Engineering, The University of Melbourne, Australia. He has expertise in multiscale modelling of concrete, numerical modelling of concrete structures and microstructural characterisation. He has published several journal papers related to multiscale modelling and his PhD thesis was mainly focused on multiscale modelling of high-strength concrete. He has developed new methods and theories to characterise material on the nano/micro scale to determine microstructural phases and their properties and link these properties to the macro scale.
