Today he has a PhD, has written two books, and is a college lecturer. Vicky Nanjappa profiles this knowledge seeker as we continue our series on Extraordinary Indians.

Anything is possible or shall we say nothing is impossible. V Kathiresan's story proves that. This school dropout, who used to work as a driver for A P J Abdul Kalam, ensured that his dream turned into a reality at the age of 47.

"One day while driving, Ayya suggested that I should resume my studies. He told me that the best way to go about it was through long distance education. Ayya used to lecture several students about the importance of education. I used to listen to him speak and got inspired."

His struggle against the odds has become an example for his students. Santhosh Mani, a student at the college, says his teacher's story is like a fairy tale. "We complain so much about work load and the other burdens of life," says Mani. "Today I look up to him and tell myself that anything is possible. It is just a matter of dedication and effort."

Dr Kathiresan lost his father very early in life and had no choice but to support his family. Though he was always fond of studying, financial problems compelled him to drop out of school. "It was one of the most painful decisions of my life, but I accepted it as a way of life."

He trained as an electrician and joined the Indian Army in 1979. His first posting was in Bhopal, then Sikkim followed by Hyderabad.

He started working towards completing his school education. He appeared for the Class X and then Class XII examinations privately and obtained a BA from Madurai Kamraj University through distance education. He then went on to do an MA in political science.

"I noticed that as the days passed, the urge to pursue higher studies started creeping into my system. I did my BEd followed by an MEd from Madras University and then an MPhil from Kamraj University. I then did law and finally a PhD from Manonmaniam Sundaranar University."

In 2001, he passed the teachers' recruitment exam, and was selected on merit. His first assignment as a teacher was at Kovilpatti where he worked for eight years. Apart from this he has written four books on history and a travel guide for the Tirunelveli district in Tamil Nadu.

"After completing my PhD, I called Ayya and told him that I had got a job also. The kind words and the appreciation that he gave me are more important than anything else in this world. He had faith in me and I did not let him down."

Dr Kathiresan cannot forget the role his wife Kasthuri played in his entire struggle. A teacher herself, she was a rock through his difficult times. The couple have decided to ensure that their son Raghavan, who is in Class XII, gets sound academic grooming.
