He has obtained spectacular results in prime number theory, especially on the small gaps problem and he solved the famous problem of Paul Erdos on large gaps between primes. Thus he has taken the world of number theory by storm. He is only 27 and the SASTRARamanujan Award is the first major prize to recognize his great work.
