  About Me:

Hi This is V Balakrishnan. I am currently a graduate student at Johns Hopkins University. I work in the CLSP(Center for Speech and language Processing) laboratory.
My advisor is Dr.Sanjeev Khudanpur
I did my Undergraduate from IIT Madras from the Department of Electrical Engineering.

  Research Interests:

My research interests include Automatic Speech Recognition, Speech Processing and Machine Learning. I currently work in collaboration with cirl where we apply our speech recognition and machine learning algorithms to analyze dextrous motions.

  Other Interests:

Apart from research, I do recreational mathematics and programming puzzles. I have won several online programming and puzzle competitions. I am consistent solver of problems in projecteuler which is my alltime favorite puzzle solving site. I am usually ranked in the top 10 always. I have solved all of the 261 problems so far.

I am currently trying to become a red coder in topcoder and eventually a target. If anyone has any suggestions on how I can go about achieving this, please email me at balakris_v(at)yahoo.com. I would be pleased to know your suggestions.
Here are some of the sites which I frequently visit:
codechef
IBM ponder this

Project Euler
mathpuzzle
qbyte
physicsforums


Recent news

I came first in this months' codechef programming challenge. Here is the link for it. I have been consistently coming in the top 5 rankings, but this is the first time I have ever won.
