My broad area of research are the fundamental particles and the forces among them. This are very well described by theories with certain properties, called gauge theories. In order to test a gauge theory, one should make a quantitative prediction which should then be confronted with the experimental results, obtained at particle accelerators. In order to make quantitative predictions (e.g. what will happen, according to my theory, if I collide a particle of type A moving at velocity v1 with a particle of type B moving at velocity v2) one should usually perform extremely hard calculations, and sometimes the complexity of these calculations can hide the structure of the gauge theory. Super-symmetric gauge theories are toy models in which it is simpler to make calculations, but which still retain the basic features of the true gauge theories of nature. Over the last few years, supersymmetric gauge theories played a fundamental role in theoretical physics, as it was understood that they (sometimes unexpectedly!) connect several areas of physics and even mathematics. This connections usually take the form of a duality, which relates two completely different theories. My area of research is super-symmetric gauge theories and more precisely their dualities to other theories, relevant to other areas of physics and mathematics. The impact of my work is mostly theoretical, but it is becoming more and more evident that the above dualities will play an important role in understanding the final theory of the fundamental particles and the forces among them. Such a final theory is expected to explain every fundamental phenomenon of nature.
