The Standard Model of physics is an extremely well tested theory which has been successfully verified experimentally to high precision on earth.  Despite these successes the Standard Model breaks down and is incomplete.  For example we can neither explain the full cosmological evolution of our universe nor the quantum mechanical aspects of extremely dense objects.  String theory holds great promise in resolving some of these outstanding issues and is the subject of Professor John Wang's research.

In particular John Wang's research lies at the interface between cosmology and string theory.  His work is motivated by the desire to understand the qualitatively new features of time dependent backgrounds such as the early inflationary universe and the current accelerating epoch.  He has been involved in the study of special classes of new objects in string theory (Spacelike branes, hyperbolic cosmologies, imaginary black holes), some of which he helped uncover. In addition, Professor Wang is interested in issues surrounding open and closed string tachyon condensation.

In terms of research opportunities, Professor Wang is committed to providing research opportunities to any interested students.
