My work on symmetries of string theory is on what is known as strong-weak coupling duality, or S-duality.
-
One of the main successes of string theory is that it has been able to unify the general theory of relativity, which describes gravity, and quantum mechanics.
-
My work on black holes was on the connection between black holes and elementary particles.
-
The beauty of string theory is that it is all about mathematics. For that, you don't need resources or labs. Just sit in your room and do the maths.
-
To me, the most exciting thing about the discovery of the Higgs particle is that its existence was predicted fifty years before its discovery through experiment.
-
Theoretical physics hardly requires any research funding, so I never felt the need. The overall government and institutional support has been good enough for my work.
-
The beauty of science is to imagine more than we can prove. And string theory gives you a radically different interpretation of the universe.

Doing physics is a lot of fun if you like it.
