I am a PhD student in Electrical and Computer Engineering at Carnegie
Mellon University since August, 2005 and expect to graduate in May,
2010. The subject of my thesis is "Large Scale Dynamic
Networks: Performance Analysis and Filtering". My thesis advisor is
Prof. Jose' Moura, ECE, CMU. I
also work closely with Prof. Kavita Ramanan, Math,
CMU.
I completed my undergraduate degree (BTech) in Electronics and Electrical
Communication Engineering from the Indian Institute of Technology,
Kharagpur, India, in May 2005. I was advised by Prof. Mrityunjoy
Chakraborty, ECE, IIT, Kharagpur and the subject of my thesis was "Block
Floating Point (BFP) implementation of adaptive signal processing
algorithms".
