He is known for the proposal of the para-string theory, construction of modular invariant partition functions for WZNW models via the orbifold method, classification of 11-dimensional supergravity solutions with a quotient structure, and discovery of non-commutativity in D-branes of string theory.
He is also known for research work in superstring theory and Yang-Mills theory.
Farhad Ardalan and some other prominent Iranian physicists, e.g. Reza Mansouri , Mehdi Golshani have been among the main architects of theoretical physics in Iran.
