Dr Gayan completed his PhD in Mechanical Engineering from University of Southern Queensland in 2013. He obtained his BSc. Engineering degree from Department of Production Engineering, University of Peradeniya and worked as a lecturer in the same department for three year. He completed his MSc. in Industrial Automation from the University of Moratuwa, Sri Lanka in 2009. He worked as a lecturer for Uva Wellassa University of Sri Lanka for one year before starting his PhD at University of Southern Queensland. Upon completion of his PhD, he worked as a Postdoctoral research fellow for one and half years at USQ. He joined the Federation University as a lecturer, mechatronics in year 2014.

In his PhD, he worked with The Boeing Company to develop monitoring system to detect damage in advanced composite structures using embedded fibre optic sensors. He currently holds two patents and has published more than 20 research articles as journal and conference papers. His research expertise includes mechatronics systems, structural health monitoring, fibre optic sensors and artificial intelligence.
