theoretical physicist Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics, which uses experi ...

string theory In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and intera ...

. He has made notable contributions to the theory of AdS/CFT conjecture—for example, in 2002 regarding the duality between strings on pp-wave spacetime and Berenstein–Maldacena–Nastase operators in ''N=4'' supersymmetric Yang-Mills theory, together with Juan Maldacena and Horațiu Năstase, and more recently (since 2004) on the matrix model of BPS ( Bogomol'nyi–Prasad–Sommerfield bound) states in ''N=4'' supersymmetric Yang-Mills theory.
