Profile

Dr. Damayanthi Dahanayake is a graduate from Institute of Chemistry, Ceylon. She has obtained a BSc in Natural Science from Open University, MSc in Analytical Chemistry from University of Colombo, MBA from Open University, and a PhD in Material Science from University of Peradeniya.

She has worked in dynamic fields within her career of 20 years before joined NSBM. Tea chemistry exposure for nine years in Tea Research Institute, Talawakelle, and Sri Lanka Tea Board, Colombo has given her the opportunity to be specialized in chromatography and spectroscopy. She has worked in Sri Lanka Institute of Nanotechnology for more than 10 years specializing in electron microscopic techniques and other nano-characterization techniques. Her PhD work was mainly focused on the study of two-dimensional materials using advanced electron microscopy. She has worked as a senior lecturer in SLINTEC Academy for postgraduate students. She has involved in different research areas and some of the highlights published in international journals are given below. She has been recognized with presidential awards for scientific research in 2016 and 2017.
