Ashoke is known for his brilliant contributions to unravelling the structure of supersymmetric quantum field theory and superstring theory. He was a leading figure in developing relationships between conformal field theories, string theory and string field theory. His profound insights into the duality symmetries of N=4 supersymmetric Yang–Mills field theory led him to predict and confirm the existence of Dyon-monopole bound states that sparked an explosion of activity in related areas of physics and mathematics. He has been a leading figure in these developments, particularly in the application of string theory methods to determining quantum properties of black holes as well as the structure of Yang–Mills quantum field theory.
