I'm pursuing my Ph.D. under Prof. Jinia Roy at the Wisconsin Electric Machines and Power Electronics Consortium (WEMPEC). My research spans pulsed power systems, AI-driven converter control, renewable energy interfaces, and bidirectional switch characterization.

• Interests: Power systems, power electronics, electric machines & drives
• Research Themes:
  • Pulse: Marx generator-based pulsed power, magnetic confinement fusion, DBD applications, power pulsation buffer (PPB) control
  • AI: Physics-informed neural networks (PINNs), spiking neural networks (SNNs), reinforcement learning-augmented MPC for power converters
  • Renewable: Electrolyzer EIS characterization, multi-port boost converter for hybrid power sources
  • BDS: Four-quadrant double-pulse test for monolithic bidirectional GaN switches
