## Mathematician

Indian American mathematician and statistician best known for his work in design theory, finite geometry and the theory of error-correcting codes.

Invented the notions of partial geometry, strongly regular graph.

Started a systematic study of difference sets to construct symmetric block designs.

Noted with Sharadchandra Shankar Shrikhande and Ernest Tilden Parker for disproving Euler's Conjecture on Orthogonal Latin Squares.

Not to be confused with Satyendra Nath Bose, after whom the boson was named.
