About
Rangana W. G. has been serving as a Lecturer in the Department of Electrical and Information Engineering, Faculty of Engineering, University of Ruhuna, Sri Lanka, since October 2025. He holds a Bachelor of Science in Engineering (Honours) degree in Electrical and Electronic Engineering, specializing in Electronics with a minor in Biomedical Engineering, from the University of Sri Jayewardenepura, where he graduated with First Class Honours and received Dean’s List Awards in Semesters 7 and 8.
His research interests encompass Artificial Intelligence, Machine Learning, Biomedical Signal Processing, Medical Image Processing, Computer Vision, and Neuro engineering. His previous research experience includes developing novel multi-view deep learning models for the early detection of Alzheimer’s disease using structural magnetic resonance imaging (MRI), wavelet-based fetal electrocardiogram (ECG) extraction, and EEG signal analysis. His broader research interests extend to Computational Neuroscience, Brain–Computer Interfaces, and AI-driven biomedical technologies.
He is passionate about exploring emerging technologies and translating innovative research into practical solutions to address challenges in biomedical engineering. Beyond teaching and research, he is actively involved in undergraduate project supervision, mentoring students in developing technical expertise, research skills, and innovative engineering solutions. He also contributes to departmental administrative activities and academic coordination, supporting the department’s academic and research activities.
