My research interest primarily focuses on the application of control theory to analyze and manage the dynamic behaviour of integrated power systems, particularly in the context of high renewable energy penetration. I am especially interested in developing robust and adaptive control strategies that ensure the reliability, efficiency, and sustainability of modern power grids. In addition to control design, I also work in the modelling and simulation techniques for modern power systems with significant integration of inverter-based resources and distributed generation.
