He was a long-time resident of Edmonton, Canada.Subbarao was born in the small village of Yazali, near Bapatla, Guntur district, Andhra Pradesh, India. He received his master's degree from Presidency College, Madras in 1941. He went on to complete a doctorate in functional analysis, advised by Ramaswamy S. Vaidyanathaswamy. He worked at Presidency College, Madras, Sri Venkateswara University, and the University of Missouri, before moving in 1963 to the University of Alberta, where he spent the rest of his professional career.In the 1960s Subbarao began to study the congruence properties of the partition function, p(n), which became one of his favourite problems. For example, he conjectured that if A and B are integers with 0 ≤ B < A, there are infinitely many n for which p(An+B) is even and infinitely many n for which p(An+B) is odd. This conjecture is practically proved. Ken Ono showed that the even case is always true. As for the odd case, if there is one number n such that p(An+B) is odd, then there are infinitely many such numbers n.
