    Family Profile:

  • I am from a small village called Udma (Udayamangalam) in North Malabar region ( Kasaragod District) of Kerala state. I had my school education in Government High School Udma, and college education (Pre-Degree and B.Sc.) at Goverment College Kasaragod, about 15 kilometers from my village. My interests, other than Mathematics, include philosophy and spirituality.

    I lost my father (Chandu Nair) when I was barely 13 years old. My mother (Meloth Parvathi Amma) is now 90 years old and living in the village. I have four sisters (Padmavathi, Parvathi, Karthiayani, Lakshmi) and a brother (Chandra Sekharan). Sisters are all married and settled in the nearby villages, and brother and his family are living in Dubai.

    I live in the IIT Campus along with my wife Sunita, and daughters Priya and Sneha. My wife is a Professor of Chemistry at SSN College of Engineering (Kalavakkam) about 35 kilometers from IIT Campus. Priya is doing her Ph.D in Bio-Medical Engineering at Arizona State University USA and Sneha is doing BE in Bio-Medical Engineering at SSN College of Engineering.
