Synopsis:

My primary research interests are in designing and implementing power conversion circuits. In power conversion systems, my research focuses on developing compact and efficient next-generation power electronics and extend this work to wireless power transfer for electric vehicles, biomedical devices and industrial applications. Also, I am interested in developing and utilizing wideband gap devices in high-power resonant converters operating at high frequencies.
