 "If I have seen further it is only by standing on the shoulders of Giants" - Isaac Newton

On the shoulders of the masters:
I have been lucky to learn from the masters. I had great teachers at IITM, starting with my PhD adviser/mentor Prof. Arindama Singh, I learned analysis under the tutelage of Prof. S. H. Kulkarni, Prof. M. T. Nair, and Prof. P. V. Subrahmanyam. In IITM we also had a weekly seminar series which I attended fervently. Here is a list of other Professors (from other institutes in India) who's lectures I have attended in the past few years.
