IEEE Member'24About
I am a Postdoctoral Research Fellow at the Living Digital Systems Lab, School of Computing, University of Nebraska–Lincoln. I have been affiliated with the University since 2022, and in 2024, I held the position of Research Engineer.
I earned my Ph.D. from South East Technological University, Ireland, in 2024, where my doctoral research focused on Exploring Molecular Communication and Gene Regulation-Based Biocomputing of Bacteria. I received my Master’s degree in Information Technology, specializing in Cybersecurity, from the Sri Lanka Institute of Information Technology (SLIIT) in 2017, and my Bachelor of Science from the University of Ruhuna, Sri Lanka in 2013.
Research Interests
Gene Regulatory Neural Networks
A GRNN is a gene regulatory network interpreted as a functional neural network for biocomputing inside living cells.
Bio-inspired Computing
Algorithms inspired by bacterial learning, designed for adaptive, decentralized, and energy-efficient computation.
Biocomputing
Computing using living bacterial cells instead of silicon, harnessing gene regulation and cellular processes.
Agent-based Simulation
Individual agents with defined behaviors interact to simulate complex system dynamics.
Molecular Communication
Biological systems transmit information using molecules as signals, enabling cell-based data processing.
Biological - AI
Utilizing the intelligence of biological entities to develop adaptive, efficient, and life-like computing systems.
