[5][6] Raju advanced a potential resolution of the black hole information paradox,[7] which is based on the idea that "all the information inside a black hole can be recovered from outside" in quantum gravity.

[8][9] Together with Kyriakos Papadodimas, Raju formulated the Papadodimas-Raju proposal for black holes [10][11] Raju was part of a collaboration that proposed the utility of the Mellin transform in AdS/CFT arguing that it provided a "natural language" for correlation functions.

[12] Raju was part of a collaboration that developed an "index" for quantum field theories with super-conformal symmetry.

[14] He is currently a professor at the International Centre for Theoretical Sciences of the Tata Institute of Fundamental Research.

[28][29] Raju was part of a group of scientists who argued that the 2019 Indian Citizenship (Amendment) Act was discriminatory.
