Theoretical Physics and Cosmology

DESCRIPTION

Research is in particle physics and cosmology, and in particular astroparticle physics, with a focus on the physics of the early universe. Expertise ranges from inflation and theoretical models of quantum gravity, to detailed predictions of particle-physics models for indirect and direct dark matter searches and particle phenomenology, including collider tests of interesting particle physics models, such as supersymmetry and large extra dimensions.

Interests:
An important part of my work deals with functional methods in Quantum Field Theory (Scwhinger-Dyson equations, Exact Renormalizarion equations and alternatives, ... ), applied to different areas of High Energy Theory, including Particle Physics, Strings, Cosmology. I have also used Quantum Field Theory for the effective description of High Temperature Superconductivity.

Interests:
My primary research is particle physics beyond the Standard Model, but I also stray into related areas of high-energy astrophysics and cosmology.

Within particle physics, I am particularly interested in predictions for collider experiments and the interpretation of their results, and my interests in astrophysics and cosmology include dark matter and strategies to detect it, as well as dark energy and cosmological inflation.

Specific research topics include the Higgs boson (or whatever replaces it), searches for it at CERN's Large Hadron Collider (LHC), and its possible connections with matter-antimatter asymmetry and the generation of matter in the Universe. Much of my research concerns supersymmetry, which I consider to be one of the most promising possible extensions of the Standard Model, and I am working actively on searches for supersymmetric particles at the LHC and as astrophysical dark matter.

I am also interested in models of quantum gravity, particularly those derived from string theory, and am in quest of possible experimental probes of such models, either in accelerator experiments or in high-energy astrophysics and cosmology

Interests:
Low dimensional systems (including superconductors), with emphasis on understanding strong correlations, and in exploiting the similarities of the underlying quantum field theory to elementary particle physics; models for (stringy) quantum gravity, in which the gravitational interactions behave like a stochastic medium; consequences for matter propagation in the context of current and future experimental facilities, both terrestrial and astrophysical; development and study of world-sheet logarithmic conformal field theories, with a wide range of applicability (from models in condensed matter physics to a discussion of recoil of solitonic backgrounds in string theory); Astroparticle phenomenology of Dark Matter and Dark Energy, exotic non-equilibrium Cosmological models, including stringy cosmologies. Supersymmetry Breaking in context of Particle Physics and in low-dimensional Gauge Theories (possibly of relevance to exotic quantum phases in condensed matter).
