I received an bachlors of engineering degree in electronics engineering from Pune University, India and the Ph.D. in electrical engineering from the Indian Institute of Technology, Bombay (popularly known as IIT Bombay). I worked at GDA Technologies Limited, India before joining my Ph.D. in 2009. After completing Ph.D. I have joined as a faculty at the Department of Electrical Engineering, Indian Institute of Technology, Ropar (IIT Ropar), IN in 2016, where I currently as an assistant Professor. My research interests are in analog integrated circuits and the applications they enable in sensing, and power management.

Proposed different architectures of the voltage reference circuit to solve the problems of conventional bandgap based and non-bandgap (only CMOS) based reference circuits, such as, accuracy, area, power consumption, PSNA.
Developing new switching techniques for DAC used in SA ADC. Such techniques reduce the energy consumption and helps to design low power data converters.
Taguchi method involves reducing the variation in a process through systematic design of experiments. The optimized voltage reference circuit show 20 % improvement over reported architecture for ≈ 50 % lesser supply voltage.
Novel split-gm method is presented to introduce a LHP zero. 3-dB BW of two stage op-amp is increased by 3 times for comparable phase margin.
Students are completely skilled with designing of analog ICs in IIT Ropar.
