Welcome to Kumar Appaiah's page!

Kumar Appaiah

I am a graduate student in the Wireless Networking and Communication Group as well as the Laboratory for Advanced Semiconductor Epitaxy, Department of Electrical and Computer Engineering at the University of Texas at Austin. My advisors are Dr. Sriram Vishwanath and Dr. Seth Bank.

I earned my Bachelor's and Master's degrees in Electrical Engineering from IIT Madras.

Education

Ph. D., Electrical and Computer Engineering, The University of Texas at Austin, August 2008 - present
M. Tech., Communication Engineering, Indian Institute of Technology Madras, August 2003 - July 2008
B. Tech., Electrical Engineering, Indian Institute of Technology Madras, August 2003 - July 2008

Research

I am working towards studying the benefits and performance of multiple-input multiple-output (MIMO) concepts in optical systems. In particular, I aim to study different signaling as well as signal processing techniques which would enable efficient MIMO communication over optical fibers.

More about myself

I hail from the Fort City Vellore, North Arcot in the state of Tamil Nadu in India, though my home is the coastal city of Chennai.

I am a free software enthusiast, and try to contribute bits of code to several free software projects. I spend a lot of my time contributing to the Debian project, and use Debian GNU/Linux for most of my work. In addition, I also enjoy bicycling, both for my daily commute as well long bicycle rides for pleasure.

Texas Travels

I attempt to chronicle my travels around Texas here.
