National and International Research Collaborations
The Department of Electrical and Electronic Engineering has a strong research environment. Its own postgraduate program offers research based degrees/diplomas such as PGDip, MSc.Eng, MPhil and PhD. The department receives funds from various research grants through the university and government and also through collaborations that the department has with the industry and foreign universities and other institutes. Below, you will find a collection of ongoing and recent research collaborative projects of our members.
PROJECT: AI and Signal Processing for the Smart Grid and Renewable Energy Integration
DEEE Members: Prof. Janaka Ekanayake, Prof. G.M.R.I. Godaliyadda, Prof. M.P.B. Ekanayake.
This research project was funded by two consecutive grants from the National Science Foundation of Sri Lanka. Lanka Transformers and LTL holdings also supported this work with resources and support. There was a PhD student that graduated from a subproject in this thrust area.
