I am a PhD candidate at Newcastle University in the Sustainable Electrical Propulsion CDT, working with Dyson on current source inverter drive solutions for ultra-high-speed electrical machines. My research focuses on power electronics, electrical drives, wide-bandgap devices, machine design, finite element analysis, and experimental validation of high-speed motor-drive systems.

Before joining Newcastle, I worked as a research engineer at METU PowerLab on electromagnetic launchers, pulsed-power systems, generator refurbishment, and renewable generation forecasting. My work spans systems from grid-scale hydro generators to 100 krpm machines and high-current pulsed-power electromagnetic launchers.
