Dr Charith Rathnayaka is currently a Lecturer in the School of Science, Technology and Engineering at the University of the Sunshine Coast (USC) and Senior Fellow of the Higher Education Academy (SFHEA). He is also an Adjunct Lecturer at the Queensland University of Technology (QUT). Charith conducts his research in the area of Computational Mechanics. His work specifically focuses on better understanding the mechanical response of soft matter under different conditions as caused by various natural and man-made circumstances. Charith conducts further research in the area of Engineering Education focusing on how to create innovative learning and teaching experiences through peer programs and digital learning.

Charith completed his PhD at QUT, having previously completed a Bachelor of Engineering (Honours). His PhD, in the field of Computational Mechanics, was awarded in December 2017. In recognition of the excellence of his doctoral research, Charith was awarded QUT Outstanding Doctoral Thesis Award (Executive Dean’s Commendation Award). During his PhD, Charith successfully developed the world’s first meshfree computational mechanics-based plant cellular drying model. In doing so, Charith used Smoothed Particle Hydrodynamics (SPH) and Coarse-Grained methods to develop advanced computational models with the aid of High-Performance Computing (HPC) technologies. Charith has been capitalising on these skills and knowledge to conduct further research in multidisciplinary domains of engineering and science.

Charith conducts his teaching in multiple sub-fields of Engineering such as Thermodynamics, Fluid Mechanics and Heat Transfer. In 2018, Charith was nominated for a Vice Chancellor’s Excellence Award at QUT based on his highly successful teaching efforts. Charith’s body of work in the area of Engineering Education was also recognised through the award of a Senior Fellowship of UK Higher Education Academy (SFHEA).
