About

On October 2014, I defended my Doctoral Thesis under the supervision of Prof. Roy P. Paily in the Department of Electronics & Electrical Engineering, Indian Institute of Technology Guwahati (IIT-G). Thereafter, I joined as Assistant Professor in the Center for VLSI and Embedded System Technologies (CVEST), International Institute of Information Technology Hyderabad (IIIT-H). I received Early Career Research Award from the Science and Engineering Research Board (SERB), Department of Science & Technology (DST), Government of India, in the year 2015. Currently, I hold the position of Associate Professor in the School of Computing and Electrical Engineering (SCEE), Indian Institute of Technology (IIT) Mandi. In the year 2018, I was selected as the Visiting Assistant Professor at the Blekinge Institute of Technology, Karlskrona, Sweden, under the European Erasmus+ International Credit Mobility Programme. At IIT-Mandi, I am heading a very enthusiastic research group that is working in the field of designing efficient algorithms & digital VLSI architectures, its transformation into ASIC chip or FPGA prototype for the real world applications of signal processing, wireless communication, deep neural network, forward-error-correction channel decoders, cognitive radio, and cooperative spectrum sensing. We have published our various research works in more than 22 reputed journals and 32 tier-1 conferences. In the year 2020, I have been elevated to the Senior Member of Institute of Electrical and Electronics Engineers (IEEE), USA.
