Hi!

I'm a Ph.D. Research Scholar at the Electrical Engineering department, IIT Madras, working under the guidance of Prof. K. Giridhar and Prof. Sheetal Kalyani.

Background

I hail from Karaikudi, Tamil Nadu. I completed B.E. (Electronics and Communication Engineering) in 2017 from PSG College of Technology, Coimbatore. During my UG, I've worked on design of a smart wind farm system based on Xbee internetworking which focused on wind farm management with a scope for smart grid integration using an Xbee network. I've also worked on realization of zero frequency filter for detection of voice activity and speech recognition.

I did my final year undergraduate project as an intership in IIT Madras under Prof. K. Giridhar during Jan-May 2017. This work focussed on the study of distribution of SINR for single operator and multi operator 4G wireless networks.

After finishing my under graduation, I joined IIT Madras as a Ph.D. scholar in July 2017. My interests are signal processing and estimation, wireless communication and non parametric algorithms. I currently work on Signal processing techniques for Distributed Radar Systems, parameter-free subspace clustering and link abstraction techniques for non linear receivers in interference limited OFDM systems.
