About:

Hello, welcome to my home page. I am an Assistant Professor in the Department of Electronics and Communication Engineering at Indian Institute of Information Technology, Guwahati. I joined IIITG in July, 2018. Prior to that, I did PhD from IIT Kharagpur (Year of awarding PhD degree: 2018). I obtained the M.S. degree from the Department of E.&E.C.Engg., IIT Kharagpur in 2011, and the B.E. in E.&T.C. from Bengal Engineering and Science University Shibpur (currently, Indian Institute of Engineeering Science Technology Shibpur) in 2007.

Research Interests:

Adaptive Signal Processing, Sparsity Aware Adaptive Filters, Distributed Adaptive Filtering / Adaptive Networks, Signal Processing for Digital Communication, Signal Processing for Audio and Acoustic Applications and some other topics.

Teaching:

At IIITG, currnetly I am teaching the following courses:

  • EC241: Signals and Systems
  • EC646: Statistical Signal Processing
