He has over 200 publications, three books and four patents. He is currently Transaction Review Chair of the Power Electronics Devices and Components Committee of the IEEE Industry Applications Society. He has been Associate Editor of the IEEE Transactions on Power Electronics and the IEEE Transaction on Industry Applications. His area of research is power electronics. It is a growing research area with many applications from renewable energy to transportation to the power grid. In particular, penetration of power electronics is leading to revolutionary changes in the nature and characteristics of the utility power grid, providing significant research opportunities. His research interests are in control of power electronics power distribution systems, system identification of power electronics systems, physics-based modeling of power semiconductor devices, and modeling and simulation.

Research Interests

• Control of multi-converter systems: model the emergent behavior due to interactions among closed-loop-controlled interconnected converters and devise control strategies to improve stability and performance.
• Novel control and system identification techniques in power electronics: methods to perform online stability measurements and control adaptation to improve system stability.
• Applications of artificial intelligence and machine learning in power electronics: application of digital twin and deep learning techniques to power electronics systems.
• Two-phase cooling for power electronics systems: two-phase cooling has the potential to significantly reduce converter system size and weight and improve reliability.
• Physics-based modeling of power semiconductor devices: develop, implement and validate physics-based models for various bipolar and unipolar power semiconductor devices both in silicon and wide bandgap materials such as silicon carbide and gallium nitride.
