In spite of taking up a job quite remote from mathematics, Ramachandra studied number theory all by himself in his free time. Especially the works of Ramanujan. Ramachandra completed his graduation and post graduation from Central College, Bangalore.
He obtained his Doctor of Philosophy from University of Mumbai in 1965.
His doctorate was guided by K. G. Ramanathan.
Ramachandra worked as a clerk at the Minerva Mills where Ramachandra"s father had also worked. Later, he worked as a lecturer in BMS College of Engineering. Ramachandra also served a very short stint of only six days as a teacher in the Indian Institute of Science, Bangalore.
Ramachandra went to the Tata Institute of Fundamental Research (Tata Institute of Fundamental Research), Bombay, for his graduate studies in 1958.
Between the years 1965 and 1995 he worked at the Tata Institute of Fundamental Research and after retirement joined the National Institute of Advanced Studies, Bangalore where he worked till 2011, the year he died. During the course of his lifetime, he published over 200 articles, of which over 170 have been cataloged by Mathematical Reviews.
His work was primarily in the area of prime number theory, working on the Riemann zeta function and allied functions. He also contributed to many other areas of number theory.
His Erdős number was 1.
In 1978 he founded the Hardy–Ramanujan journal, and published it on behalf of the Hardy–Ramanujan society until his death.
