I was born and raised in the southern Indian coastal city named Chennai (fondly called Madras). I am currently pursuing my doctoral studies under the supervision of Prof. Henry Pfister and
Prof. Robert Calderbank in the Information Initiative at Duke (iiD) group of the Department of Electrical and Computer Engineering at Duke University, Durham, NC, USA. Prior to this, I completed my Master of Science (M.S.) degree at Texas A&M University, where I worked on the construction of Cyclic Polar Codes. I was a graduate research intern during the summer of 2015 at Alcatel-Lucent Bell Labs, Stuttgart, Germany, where I worked on the analysis of Spatially-Coupled LDPC ensembles over burst erasure channels, under the supervision of Dr. Laurent Schmalen and Dr. Vahid Aref.

My general research interests are in the realms of information and coding theory (both classical and quantum), compressed sensing, statistics and their applications. Currently, I am working on the construction of quantum codes and synthesis of their fault-tolerant logical operators for quantum computing. I am also interested in codes and decoding algorithms for quantum communications. I am a Student Member of the IEEE and the Information Theory Society.

I love pencil sketching and like to read about science, philosophy and life. I play cricket, volleyball and bowling. I am a novice writer and hope to disseminate productive thought and knowledge through this powerful platform called internet. My old blog is here.

Jan 2018: Our paper on the Finite-Length Analysis of Spatially-Coupled Regular LDPC Ensembles on Burst-Erasure Channels has been accepted for publication in the IEEE Trans. on Inform. Theory.

Sep 2017: I am the teaching assistant for the course on Error Correction Coding taught by
Prof. Robert Calderbank and Prof. Henry Pfister.

July 2017: I will be participating in the 5th Beyond I.I.D. in Information Theory Workshop.

June 2017: I am presenting a poster on Deterministic Compressed Sensing and Recovery of Large Supports at the North American School of Information Theory.

January 2017: I am the teaching assistant for the course on Digital Audio Processing.
