I am a string theorist and my research has focussed on various aspects of M-theory, F-theory, Matrix-models, Noncommutative geometry and the newly discovered six-dimensional theories and their large N limit. Over the past decade a lot of progress has been made in the study of strongly coupled supersymmetric field theories and string theories. The discovery of new field theories in six dimensions is one of the interesting recent developments. Their fundamental formulation is still mysterious but their existence was deduced from string theory. These theories are inherently strongly coupled quantum systems and they shed new light on nonperturbative and strong-coupling effects in gauge theories.
In our recent project we explored field theoretic models that exhibit nonlocal behavior. These models have emerged in the research on noncommutative field theories and their nonlocal behavior is related to macroscopic strings that become light under certain conditions. A better understanding of these models might shed more light on the microscopic structure of space and time.
