Research Interests<\/strong><\/h2>\n

My current interests include Cosmology and Black Holes<\/a>\u00a0,\u00a0Two-Time Physics<\/a>\u00a0(2T-Physics) and\u00a0String Field Theory<\/a>\u00a0(SFT). My long-term goal is the construction of the unified theory at the fundamental level.<\/p>\n

My research is driven by some of the current questions in Cosmology, the Standard Model of elementary particles, and unification of forces including quantum gravity in the framework of string theory or M-theory. The mysteries that are hoped to be resolved include the physics of the very early universe and how it determined the gauge symmetries (forces) and the families of quarks and leptons (matter) that we observe today. Once the fundamental theory is constructed it is likely that it will suggest the best approach to answer our current mysteries, including dark matter, dark energy and a host of issues related to masses and interactions of quarks, leptons and force particles.<\/p>\n

All the physics we know with certainty today at microscopic or macroscopic distance scales is embodied in principle in the fundamental laws described by the Standard Model of Particles and Forces, and in General Relativity.\u00a0\u00a0In 2006 I discovered the\u00a0\u00a02T Standard Model<\/a>\u00a0and in 2008\u00a02T-Gravity<\/a>, both in 4-space and 2-time dimensions.\u00a0\u00a0Supersymmetric 2T-field theory<\/a>\u00a0in 4+2 dimensions\u00a0has also been achieved\u00a0during 2007-2009. From the point of view of these 2T field theories, as well as 2T particle dynamics that I developed since 1995, all known physical phenomena experienced in 3-space and 1-time dimensions, as described in 1T-physics, appear as various \u201cshadows\u201d of phenomena in 4+2 dimensions. 2T-physics captures \u201chidden\u201d properties of physical systems in 3+1 dimensions that are systematically missed by the usual 1T-physics formulation (see simplest\u00a0example<\/a>). The existence of such verifiable predictions, that 1T-physics can only confirm but cannot foresee systematically, show that 2T-Physics is a larger unifying framework and an unavoidable completion of 1T-physics. I therefore expect that the methods of 2T-physics will prove to be essential in the construction of the ultimate unified theory as well as in a more complete description of all physics at all scales of distance or of energy.<\/p>\n

I emphasize symmetries and supersymmetries in much of my research on particle physics, field theory and string theory. From time to time the symmetry structures in physics have led me to discover new physical concepts, such as Two-Time Physics (2T-Physics), as well as a few new\u00a0structures in Mathematics or Mathematical Physics<\/a>, in particular in\u00a0supergroups, non-compact groups, and noncommutative geometry. This activity also took me on side trips into applications of symmetries in other fields of physics. Consequently,\u00a0supersymmetry in nuclear physics<\/a>\u00a0was experimentally confirmed\u00a0as an approximate symmetry of bosonic and fermionic nuclei.<\/p>\n

Some of the theoretical computations I did in the past on the Standard Model, gauge theories, and grand unification, are currently of experimental interest. In\u00a0particular\u00a0the first computation of the weak interaction contribution to the\u00a0anomalous magnetic moment of the muon<\/a>\u00a0has recently been confirmed by measurements performed more than 30 years later.
