Theoretical work in gauge theories, string theory, quantum gravity and their mathematical aspects. Special emphasis on quantization of non-linear theories, non-perturbative methods especially for supersymmetric gauge theories, duality symmetries and supersymmetric solutions of supergravity theories. Also, two dimensional conformal and integrable field theories, their relevance for the vacuum structure of string theory and applications of large N limit field theoretic techniques.

My current research interests lie in the field of phenomenology of supersymmetric extensions of the Standard Model, in particular, models with broken R-parity. The subject of the study is both phenomenological (predictions for collider searches) and theoretical (renormalization properties of these models). Connected with the above is the construction of models free from ultraviolet divergences - finite models. Another direction is studying the dark matter problem in the framework of low-energy supersymmetry, namely, calculation of the cross-section of neutralino and neutralino-slepton ahhihilation, and predictions of the allowed parameter space based on the global fit analysis.
- Calculations of 1-loop processes involving the production of pairs of neutral gauge and scalar bosons at Colliders, in the Standard and minimal SUSY models.
- A complete analysis of the neutralino system for real and complex SUSY parameters employing the projector formalism, first used by Jarlskog in the tratment of the CKM matrix.
- The study of the neutrino ionization cross section for H, He and Ne atoms.

My scientific interests are focused on Supersymmetry. On the phenomenological side my recent activity has been concentrated on studying issues related to Supersymmetric Dark Matter and in particular in exploring wheter the lightest of the neutralinos, the LSP, can be a viable candidate for explaining the missing mass of the Universe. On the theorewtical side the construction of locally Supersymmetric five dimensional ( 5-D ) Grand Unified Models, based on N=2 SUSY, and their phenomenology has attracted my attention. Starting from the popular SU(5) gauge group, and having in mind larger patterns along with the breaking of Supersymmetry. The phenomenological study of such models, after the extra dimension is compactified , it is interesting especially when the in unification schemes, it is interesting to explore the possible gauge symmetry breaking verse size of the extra dimension lies in the TeV range.
John March-Russell is a theoretical particle physicist working on "beyond the Standard-Model" physics. This involves the development of new theories to describe the most fundamental aspects of the world around us. These include the nature of space and time, the behaviour and origin of the forces and matter we observe, the origin and very early (the 1st second and before) history of the universe, and the properties of black holes. The specific questions he works on include such ideas as that we may be living on a type of membrane in a higher dimensional spacetime, and supersymmetry, which is the possibility that the classical idea of a dimension might have a discrete intrinsically-quantum generalization.

Petros Rapidis is an experimental physicist. He studied at Stanford under the supervision of M. L. Perl where he worked with the SLAC-LBL team at SPEAR that first saw charmed particles and the tau lepton. Since then he has been at Fermilab, where he was a Wilson Fellow and now is a senior scientist. While at Fermilab he worked on neutrino-nucleon scattering and neutrino oscillation experiments, on the construction and operation of the Antiproton Source. He was a leading member of the study of exclusive production of charmonium in proton antiproton annihilation. He is now a member of the D0 group where he is leading its silicon vertex detector effort.
