Ph D (Electrical Engineering) (University of Cambridge)
Area of research: Power Electronics, Energy Storage, Electromobility, Wireless Power, Electrical Drives, Renewable Energy; I am most interested in how electric power can be generated, converted, and utilized efficiently. My main focus is on the development of efficient energy conversion processes using new power semiconductor devices along with novel converter topologies and electrochemical systems. With the electrification and automation of many aspects of our lives, it is of paramount importance that energy is converted efficiently and economically. Presently, the evolving paradigm shifts within the energy sector revolutionizes the way energy is generated via modern energy sources, the way energy is converted to different forms, and the way energy is stored using novel storage devices. Exploring new avenues in this revolutionary research domain is a challenging yet fascinating task for many contemporary power engineering professionals in today's world.
