I am an MASc student at the School of Engineering, Simon Fraser University advised by Dr. Zhenman Fang. My research interests include Customizable Computing, Unconventional Computing, Low Power Hardware Architectures, and VLSI design.
Under the guidance of Prof. Sumam David, I completed my undergraduate degree from the National Institute of Technology Karnataka in the year 2017. I then worked as a Senior Hardware Engineer at Samsung Semiconductors India Research (SSIR), Bangalore, India (June 2107 - August 2019), and as a Digital Design Engineer at Texas Instruments, Bangalore, India (August 2019 - January 2021).
So far, I have worked in multiple domains of electronic systems design ranging from embedded systems to circuit intensive digital VLSI design. In the year 2016, I was reciepient of prestigious MITACS Globalink Scholarship at University of Alberta, where I worked in the area of satellite embedded systems. Later through my industrial experience, I developed skills in SoC Design, VLSI architectures for DSP, RTL development, RTL Synthesis and RTL Design Verification.

Area and Power Optimised ASIC Implementation of Adaptive Beamformer for Hearing Aids BioCAS '17
Beamforming is a technique used in hearing aids to improve the intelligibility of target sound by reducing the interference from other directions. An efficient ASIC implementation of a two omnidirectional microphone array based adaptive beamforming algorithm is presented in this paper with various optimisations proposed at different stages of the hardware design. The beamform patterns and improvements in SNR values obtained from experiments conducted in a conference room environment were analysed to verify the working of the design. The architecture was implemented with 0.18 μm standard cell libraries. Cell area and power reports were analysed for different optimisations. The final area and power obtained are 0.054 mm 2 and 60.54 μW respectively.

FPGA Implementation of Adaptive Beamforming in Hearing Aids EMBC '17
Beamforming is a spatial filtering technique used in hearing aids to improve target sound reception by reducing interference from other directions. In this paper we propose improvements in an existing architecture present for two omnidirectional microphone array based adaptive beamforming for hearing aid applications and implement the same on Xilinx Artix 7 FPGA using VHDL coding and Xilinx Vivado ® 2015.2. The nulls are introduced in particular directions by combination of two fixed polar patterns. This combination can be adaptively controlled to steer the null in the direction of noise. The beamform patterns and improvements in SNR values obtained from experiments in a conference room environment are analyzed.

Misc
Being an Indian, I am a huge fan of Bollywood/ Punjabi songs. I also have a taste for Western music. I sing in my leisure time and work on getting the notes right :p
