I am a PhD student in the Department of Electrical and Computer Engineering at the University of California, Los Angeles, working in the Cyber Physical Systems Laboratory with Prof. Paulo Tabuada. I received my MS in Electrical and Computer Engineering from UCLA in 2025 and my BScEng (Honours) in Electrical and Electronic Engineering from the University of Peradeniya in 2023.
My research interests include nonlinear control, safety-critical control, state estimation, and optimization. My research focuses on extending the theoretical guarantees of control barrier functions to account for uncertainty in real-world systems. I aim to develop methods that are practical to implement while retaining rigorous guarantees. I have also worked on nonlinear observers with online error bounds and applications of dynamical systems theory to viral dynamics and epidemic models. I am drawn to both the mathematical foundations of control theory and its practical applications.
