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 D. Pfister 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 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 Codes over burst erasure channels, under the supervision of Dr. Laurent Schmalen and Dr. Vahid Aref.

My general interests are in the realms of information theory, statistics and their applications. Recently, I have started looking into problems in the fields of compressed sensing, quantum information theory and quantum computing, and machine learning, specifically deep learning and its theory. 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.

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

June 2017: Our paper on Spatially-Coupled LDPC Ensembles on Burst Erasure Channels has been accepted for publication in the IEEE Transactions on Information Theory.

June 2017: I presented 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.



Here is a list of my publications. You can also follow me on Google Scholar and ResearchGate (which includes unpublished notes and research).
