Work Description:
The subject of my research are weak decays of K and B mesons within the Standard Model, Supersymmetry and other extensions of the Standard Model with particular emphasise put on rare and CP violating decays like $K\to\pi\nu\bar\nu$, $B_{d,s}\to \mu^+\mu^$, $B\to \pi K$, $\epe$ and others. On the technical side my group in Munich calculated by now the NLO QCD corrections to essentially all relevant decays both in the Standard Model and Supersymmetry. On the more phenomenological side, I study the implications of these calculations and device methods to distinguish between various extensions of the Standard Model through the simultaneous study of as many processes as possible. In this context one can also determine the CKM matrix and various parameters of the physics beyond the Standard Model.

Flavour Physics and CP Violation

These lectures discuss Flavour Physics and CP Violation as seen with the help of rare and CPviolating B and K meson decays with particular emphasize put on the determination of the CKM matrix. The following topics will be discussed: i) The CKM matrix, the unitarity triangle and general aspects of the theoretical framework, ii) Particleantiparticle mixing and various types of CP violation, iii) Standard analysis of the unitarity triangle, iv) The ratio $\epe$, v) The most important strategies for the determination of the angles $\alpha$, $\beta$ and $\gamma$ from B decays, vi) Rare decays $K^+\to\pi^+\nu\bar\nu$ and $K_L\to\pi^0\nu\bar\nu$ and vii) Correlations between nonleptonic B decays and rare decays and physics beyond the Standard Model. 
Work Description:
I do research on Early Universe Cosmology. More specifically, on models of inflation based on high energy particle physics, as well as on specific signatures that these models have on the pattern of temperature and polarization anisotropies of the Cosmic Microwave Background and the large scale structure of the universe. With the recent revolution in cosmological observations we are beginning to constrain rather stringently the main alternative models of inflation. I also do research on Reheating, the epoch in which the energy density driving inflation is converted into radiation. Recent theoretical progress in this area suggests that the process could be very nonlinear, nonperturbative and very far from equilibrium, which could give rise to very interesting phenomenology, like the production of topological defects at nonthermal phase transitions, production of the primordial intergalactic magnetic fields and gravitational waves, and possibly also responsible for the origin of the matterantimatter asymmetry.

Cosmology and Astrophysics  These notes are intended as an introductory course for particle physicists interested in the recent developments in cosmology and astrophysics. I will describe the standard Big Bang theory of the evolution of the universe, with its successes and shortcomings, which will lead to inflationary cosmology as the paradigm for the origin of the global spacetime structure of the universe. Inflation is also responsible for the generation of primordial metric perturbations that will later give rise, via gravitational collapse, to the galaxies and clusters of galaxies we see in our Hubble volume. I will review the revolution in cosmological observations, mainly the microwave background and deep galaxy redshift surveys, that has allowed cosmologists to determine the parameters of our Standard Model of Cosmology with better than a few percent errors.

Work Description:
My research deals with phenomenological aspects of the existing problems in particle physics. In the last years I have been mostly concentrated on the interpretation of neutrino physics results produced by experiments determining the neutrino fluxes produced in the Sun as well as in the atmosphere together with the results from terrestrial neutrino beams from accelerator and nuclear reactors.
Neutrinos have introduced the interface between particle physics, astrophysics and cosmology which I find fascinating.

Neutrinos  Measurements of various features of the fluxes of atmospheric and solar neutrinos have provided evidence for neutrino oscillations and therefore for neutrino masses and mixing. In this lectures I will first describe the phenomenology of neutrino masses and mixing leading to oscillations in vacuum and in matter. I will then present the existing evidence from solar and atmospheric neutrinos as well as the results from laboratory searches, including the final status of the LSND experiment. I will describe the theoretical inputs that are used to interpret the experimental results in terms of neutrino oscillations and derive the allowed ranges for the mass and mixing parameters. I will also present the prospects and challenges of studying neutrino physics in approved and proposed future facilities. Finally I will briefly discuss the theoretical implications of these results: the existence of new physics, the estimate of the scale of this new physics and some lessons for different extensions of the Standard Model

Work Description:
My main research interests in recent time have been concentrated around supersymmetric models of quantum field theory and their phenomenological application in particle physics and cosmology.
I have been studying the renormalization properties of gauge field theories in extra dimensions with the aim to construct a consistent quantum field theory.
We have been also continuing the analysis of the Minimal Supersymmetric Standard Model subjected to various theoretical and experimental constraints including those coming from the Dark matter search. We performed the analysis of recent astrophysical data taking into account the neutralino contribution to the Dark matter in order to reconstruct the profile of the Dark Matter in our Galaxy.

Field Theory and the Standard Model 
The Standard Model of Elementary Particle Physics will be described. A detailed discussion of the particle content, structure and symmetries of the theory will be given, together with an overview of the most mportant experimental facts which have established this theoretical framework as the Standard Theory of particle interactions. 1. Gauge Theories: QED, QCD 2. Electroweak Unification: SU(2)_L x U(1)_Y 3. Symmetry Breaking: Higgs Mechanism 4. Electroweak Phenomenology 5. Flavour Structure of the Standard Model 
Work Description:
The central topics of my present work are the thermodynamics of strongly interacting matter and the study of high energy nuclear collisions.
Strong interaction thermodynamics is today defined by statistical QCD and shows for increasing temperaturea and/or densities a transition from hadronic matter to a plasma of deconfined quarks and gluons.
The nature and the properties of this transition have to be determined, and its experimental consequences identified.
The aim of high energy nuclear collisions is to study deconfinement in the laboratory. This implies both initial state partonic aspects, which through parton percolation can lead to geometric critical behaviour, and possible subsequent thermalization with quarkgluon plasma formation. Here again experimentally accessible signals of the different evolution stages are of primary importance.
