I work at the Computational Biology Center of IBM T. J. Watson research center, Yorktown Heights, NY, USA. My present research is exploring the use of High-performance computing and machine learning techniques for the analysis of Neuroimaging data.  I am developing algorithms to solve inverse problems in the domain of medical image reconstruction and analyze functional connectivity of the brain in the domain of fMRI data analysis.

 

In my previous life, I was manager of the high-performance computing group at IBM India Research Lab. I was privileged to work with wonderful colleagues at the IBM India Research Lab. All the wonderful work we did wouldn’t have been possible without their enthusiasm, active involvement and support.

 

My first love was communication networks followed by game theory, auction algorithms and Economics. I also held an adjunct faculty position in the Computer Science Department of Indian Institute of Technology, Delhi, where I taught courses on game theory and communications networks.
