My research thrusts are presented here.

The global transition toward electrified transportation and renewable energy is reshaping the role of power electronics. Future systems must remain intelligent, reliable, resilient, and efficient under uncertain operating conditions. My long-term vision is to advance the design, control, and digitalization of modular, intelligent, and resilient power electronic systems to enable clean energy integration and transportation electrification.

My research spans the modeling, design, and control of power electronic converters for renewable energy, transportation electrification, and future inverter-dominated grids. I work at the intersection of hardware design, real-time control, electro-thermal modeling, and digital-twin technologies, with the broader goal of improving efficiency, reliability, and resiliency in next-generation energy systems.

Research Thrust 1: Power Electronics for Renewable Energy Systems

🎯 Goal: Enhance reliability and control of renewable-integrated converters

The increasing penetration of renewable energy resources such as solar photovoltaic and wind has introduced new challenges to power quality, control, and resiliency. My early research addressed these challenges by developing advanced inverter topologies and control techniques to mitigate voltage disturbances and improve efficiency. For example, I introduced novel methods for voltage sag compensation in grid-connected PV systems, proposed inverter architectures that enhance performance under partial shading, and designed adaptive restoration schemes that simultaneously improve power quality and ensure stable operation.

To further maximize energy extraction, I developed metaheuristic-based MPPT algorithms capable of handling the nonlinear behavior of partially shaded PV systems. These contributions established a foundation for designing renewable energy interfaces that are both resilient and reliable. Looking ahead, I will extend these efforts to address the unique stability and resiliency challenges of 100% renewable grids, particularly through advanced inverter-based controls and coordinated renewable–storage integration enabled by artificial intelligence.

Research Thrust 2: Power Electronics for Electrified Transportation

🎯 Goal: Develop resilient converters and control strategies for electrified transportation

Electrified transportation systems—including all-electric ships, electric vehicles, and aerospace platforms—demand converters that are efficient and reliable under mission-critical conditions. My doctoral research advanced the Power Electronics Building Block (PEBB) concept by developing a multi-objective control and electro-thermal management framework. This work introduced predictive control methods that reduce thermal stress and extend device lifetime while maintaining power quality and integrated data-driven degradation forecasting to enable adaptive, reliability-aware operation.

Building on this foundation, I expanded the PEBB framework as a Post-Doctoral Research Associate, focusing on system-level naval applications under ONR funding. My recent work includes contributions to digital-twin development, thermal cooling approaches, dielectric scaling laws, battery storage integration, and large-scale hardware validation platforms. These projects demonstrate my ability to translate component-level innovation into scalable, mission-ready naval power distribution systems.

This thrust defines a key direction of my future research: advancing converter design, electro-thermal-reliability-aware control, and digital-twin-enabled integration strategies for shipboard, aerospace, and automotive platforms. Continued research is urgently needed as transportation systems transition toward electrification, requiring solutions that guarantee efficiency, reliability, and resilience under complex operating conditions.

Research Thrust 3: Inverter-Based Resources and Custom Power Devices

🎯 Goal: Enable stable grid operation in high-IBR environments

High penetration of Inverter-Based Renewables (IBRs) is transforming modern grids, especially under weak-grid and low-inertia conditions. This thrust addresses stability and resiliency challenges through coordinated design of inverter controls and custom power devices. My research agenda includes developing adaptive inverter controls for high renewable penetration and addressing challenges such as low inertia, weak-grid operation, and unbalanced faults; investigating advanced grid-forming control strategies for IBRs that enable stable operation in 100% renewable microgrids; and developing custom power devices (e.g., Dynamic Voltage Restorer (DVR), Distribution Static Synchronous Compensator (D-STATCOM), and Unified Power Quality Conditioner (UPQC)) that support IBRs through voltage stabilization, current regulation, and post-disturbance grid recovery.

Together, these thrusts support a unified research agenda aimed at developing intelligent, modular, and resilient power electronic systems for future renewable, transportation, and naval energy platforms.
