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 Engineering Science and Technology Shibpur) in 2007.
I also worked at the Dept. of Signal Theory and Communication, Universidad Carlos III de Madrid, Spain during 2012 - 2014 as a Visiting Researcher under an Indo-Spanish Project sponsored by the Govt. of India and Govt. of Spain.
I have also worked as a Senior DSP Engineer at the Audio Technologies and Codecs (I) Pvt. Ltd. during 2017-18.
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:
EC242: Digital Signal Processing
