Research Interests:

The main goal of my research has been, and continues to be, the application of apparently pure theoretical ideas to phenomenological needs in particle physics. One major project on which I have been working involves the application of the well established theory of strong interactions so-called Quantum Chromodynamics (QCD), to the quark model. As we know, the quark model has been the main phenomenological tool for the past 30 years but, from a QCD theoretical point of view, nobody understands why it works so well. I believe some of the results obtained in my recent papers are a first step in the direction of establishing this connection in a quantitative way.

I am also working (and I am going to continue this study) on 2 dimensional QCD2(N = ) and other "toy" models. I believe that toy models may help us to understand the nature of chiral symmetry breaking phenomena.

I am also working in the area where the particle physics and the theory of gravity overlap. I believe that this field will be the most exciting in the near future.
