Research Associate
Dr Roshan Jayathilakage
Engineering
Civil and Environmental Engineering
Roshan completed his Ph.D. at Swinburne University of Technology, Melbourne, Australia in Civil Engineering (Concrete 3D printing) in 2021. He worked as a structural engineer for one and half years at NSIENT Consulting Engineers in Melbourne and moved to Sydney to join UNSW at Sydney as a postdoctoral research associate in the school of civil and environmental engineering. His expertise are concrete 3D printing, concrete rheology, construction materials, and mix designs, concrete durability, structural design, and numerical simulation of fresh concrete and hardened concrete at meso and macro level.
