About:

I am an Assistant Professor in the Department of Electronics and Communications Engineering (ECE) at Indian Institute of Information Technology Guwahati (IIITG). I joined IIITG in August, 2019. Prior to that, I received the MS and Ph.D. degrees in Signal Processing and Communications and Digital Communications in 2013 and 2017, respectively from the University of Edinburgh (UEDIN), UK. Following that I worked at the Institute of Digital Communications in UEDIN as a research associate from 2017 to 2019. I also have industrial experience with Tata Consultancy Services, India (Lucknow & Kolkata), where I held the position of Asst. Systems Engineer from 2010 to 2012. I was an organizer for the IEEE International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), Edinburgh, UK, 2016 and until now have been involved in several projects, including two EU FP7 projects: remote radio heads & parasitic antenna arrays (HARP) and dynamic licensed shared access (ADEL), a DST UKIERI project on wireless edge caching and an EPSRC project on NoMA.

Research Interests:

My research interests lie on signal processing for wireless communications, with particular focus on 5G’s long-term evolution, including transceiver design for full-duplex radios, cognitive radio, wireless edge caching and comms-radar co-existence.
