Biography

Gihan Dissanayake currently serves as a Senior Lecturer in the Department of Civil Engineering at the University of Peradeniya (UoP), Sri Lanka. He earned his BSc (Hons) in Civil Engineering from UoP in 2007 and completed his MPhil in Civil Engineering in 2016,with ongoing PhD research in vibration-based structural health monitoring and nonlinear damping for damage detection. He is a Chartered Civil Engineer (C. Eng.) and a member of the Engineering Council of Sri Lanka. He is also a member of the Institution of Engineers Sri Lanka (IESL), Associate Member of the Society of Structural Engineers Sri Lanka (SSESL), and a Green Associate Professional with the Green Building Council of Sri Lanka (GBCSL). He has over 18 years of experience in structural design, analysis, and construction supervision, specializing in the use of Finite Element Analysis (FEA) and structural health monitoring. His research focuses on damage detection and repair in structures, and he has
published in peer reviewed journals and books. Gihan Dissanayake has contributed to both academic and professional fields, applying his engineering experience to advance the quality of civil engineering education and research.
