# John F. Stanton

Born May 3, 1961 in Sagamihara, Japan.

George Watt Centennial Professor of Chemistry at the University of Texas, and Director of the Institute for Theoretical Chemistry

## Author of:

About two hundred papers in the area of theoretical chemical physics.

## Important Contributions:

Codeveloper (with Jürgen Gauss) of analytic first and derivative techniques in coupled-cluster theory and high-order many-body perturbation theory; considerable work on the treatment of radicals and excited states via the so-called equation-of-motion coupled cluster method; developer of a quasidiabatic ansatz that extends the use of equation-of-motion methods for spectroscopic applications; investigations into symmetry-breaking effects and the ways in which pseudo Jahn–Teller interactions are represented by various quantum chemical methods; treatment of non-adiabatic effects in molecular spectroscopy; development of model Hamiltonians to treat strongly interacting systems; development of a non-Hermitean perturbation theory that is now widely used to rationalize and/or derive corrections to coupled-cluster models.
