After my M.Tech, I worked in consumer electronics industry as Senior Engineer for around 1.5 years. Following this, I joined for Ph.D in the Department of Electrical Engineering, IISc Bangalore. I did my Post-Doctoral Fellowship from State University of New York, Binghamton, USA, where I primarily worked on soft-switched AC-DC resonant converters for forklift battery chargers. Subsequently, I joined as a Project Scientist in Department of Electrical Engineering, IISc Bangalore. Here, I worked on control of AC-DC and DC-DC converters for electric vehicle application as part of a sponsored project.
