Summary Statement of Research Interests

Professor Chang studies the strong multi-electron interactions in atomic transitions dominated by multiple excitations in complex atoms. In addition to his continuous efforts on the development of general theoretical formalism related to atomic structure theory, he has also made considerable progress in the development of the state-of-art computational techniques suitable for applications on the most powerful high speed computers.
