About Me

I am a pure mathematician and work in various areas in Number Theory. Over the years I have visited many countries and various places in India relating to my work and developed a kind of all weather personality. I am a fitness freak and strongly believe in the saying A healthy mind lives in a healthy body. I love to be amongst the younger people and over the years motivated many students and Post doctoral fellows to choose healthier life which have helped them immensely in their personal lives as well as in their career. I have developed a belief that I can help many younger students not only academically but also in their pursuit for a brighter future. I love to take new challenges which brings out the best in me.
