About

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.
