|I am a theoretical physicist who has worked most of my career searching for an unifying theory for all the fundamental interactions, gravity, the strong and the weak interactions and the electromagnetic one. I am one of the founders of the so-called Superstring Theory in which the fundamental constituents of nature are one-dimensional objects, strings. This theory has been shown to give a consistent quantum mechanical description of gravity and can also include the other interactions. There has been a large effort in the international scientific society for the last thirty years to study this theory.|
I have also been involved in the study of supersymmetric quantum field theories. I am one of the inventors of the maximally supersymmetric Yang-Mills Theory. Together with my collaborators I showed that this theory is quantum mechanically finite, the first such model to be found. Later it has been shown that this field theory is dual to the Superstring Theory in the sense that strong-interaction results in one of them can be computed by as weak coupling expansion in the other. The maximally supersymmetric Yang-Mills Theory is on the one had the most simple field theory in perturbation theory, often called "the harmonic oscillator of the 21st century". On the other hand non-perturbatively it contains information about the Superstring Theory and hence about quantum gravity and perhaps about the ultimate theory of the universe.
Through a long career I have worked at CERN, Caltech, the Institute for Advanced Study and other leading institutions while having my base at Chalmers University of Technology in Göteobrg, Sweden. I have been involved and chaired many international committees and led the European Network for the Superstirng Theory for twelve years. I am a member of the Royal Swedish Academy of Sciences and the The Royal Society of Arts and Sciences in Gothenburg. I was elected a member of the Nobel Committee for physics in 2001 and left it in 2013 as the chairman.
|My present day interest is in the search for the ultimate theory of the universe. While I am not directly working on the Superstring Theory for the moment, it is behind much of the my activities. My main research activity is to study the low.energy limit in terms of the maximally supersymmetric Yang-Mills and the maximally supersymmetric supergravity theory and the relation between them and the Superstring Theory.|
Having been a member of the Noble committee for many years I also take an active interest in recent developments in quantum cosmology, astrophysics and in quantum condensed matter theory as well as in other fields on the front-line.
