Rahal Nanayakkara

I am currently a PhD student at the Cyber Physical Systems Laboratory of the Department of Electrical and Computer Engineering, University of California, Los Angeles, under the supervision of Prof. Paulo Tabuada.

Prior to that, I completed my Bachelor of the Science of Engineering (Honours) in Electrical and Electronic Engineering at the Faculty of Engineering, University of Peradeniya. During my undergraduate studies, I was supervised by Prof. Roshan Godaliyadda, Prof. Parakrama Ekanayake Prof. Vijitha Herath , and Dr. Janaka wijayakulasooriya

Undergraduate Final Year Research Project - Smart Monitoring for Biomedical Applications

My final year research project focuses on using Biomedical Signal Processing techniques to monitor the wellbeing of pregnant mothers and their unborn fetuses. We improved an in-house developed fetal movement monitoring device, by expanding it to use multiple accelerometric sensors to measure the movements and vibrations of a pregnant mother’s abdomen. This project is being conducted as a joint effort of the Faculty of Engineering and the Faculty of Medicine of the University of Peradeniya and consists of a large and diversified research team. This research experience was invaluable not only in terms of better grasping the subject matter but also in learning how to function in an interdisciplinary research team.
