I am currently a Marie Sklodowska-Curie Researcher and Ph.D. student at the School of Engineering, University of Warwick, Coventry, U.K., supervised by Prof. Xiaowei Zhao.
My current research focuses on stability analysis (both small- & large-signal) and control design for grid-forming (GFM) inverter-based resources (IBRs). Additionally, I have experience in designs/applications of controller hardware-in-the-loop and rapid-control prototyping. I am proficient in RT-LAB (Opal-RT technologies), RSCAD, PSCAD, Simulink, Matlab programming.
