Currently, I am a Software Engineer at Parallel Wireless, Inc., where I work on 5G NR protocol stack development.

Previously, I completed my undergraduate studies in the Department of Electronics and Communication Engineering at the Indian Institute of Information Technology Guwahati. During my undergraduate studies, I have worked on approximate computing and its various applications.

In my undergraduate journey, I was advised by Dr. Dip Sankar Banerjee, Dr. Soumyajit Poddar, Dr. Neeraj Goel, and Prof. Muhammad Shafique.

My research interests include approximate computing, computer architecture, networked embedded systems, healthcare IoT, and VLSI Design. I try investigating and working on interesting research problems in my free time. In case you want to know more about my research or want to collaborate with me, please feel free to send me an email.
