In 1931, when Roy joined the Department of Applied Mathematics of Rajabazar Science College at the University of Calcutta as a research associate, he used computing facilities at the newly established Indian Statistical Institute, which was founded by Professor P. C. Mahalanobis. Roy along with several talented young scholars including J. M. Sengupta, H. C. Sinha, Raj Chandra Bose, K. R. Nair, K. Kishen and C. R.

Why this record matters
The phrase “indian-born American mathematician” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q7408818. VIAF identifies the subject as 3890977. The Library of Congress control number is n84801724. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
