15. Venkatraman Ramakrishnan (1952–)

Awarded the Nobel Prize in Chemistry in 2009 for his work on the structure and function of the ribosome, Ramakrishnan has elevated India’s standing in the global scientific community.

16. Srinivasa Varadhan (1940–)

A mathematician of international acclaim, Varadhan is known for his work in probability theory. He was awarded the Abel Prize in 2007, often considered the Nobel Prize of mathematics.

17. Jayant Narlikar (1938–)

An astrophysicist, Narlikar developed the Hoyle-Narlikar theory of conformal gravity. He has also popularized science through his books and lectures.

18. A.S. Kiran Kumar (1952–)

A former Chairman of ISRO, Kiran Kumar was instrumental in several satellite missions, including the development of the Indian Regional Navigation Satellite System (IRNSS).

19. Tessy Thomas (1963–)

Known as the “Missile Woman of India,” Tessy Thomas was the project director for Agni-IV and Agni-V missiles, contributing significantly to India’s strategic defense capabilities.

20. Dr. V. Shanta (1927–2021)
