I am working on KEDR detector at the e+e- collider VEPP-4M in the Budker institute of nuclear physics in Novosibirsk. The detector could operate in the energy region from psi to upsilon mesons. In the first cycle of experiments (2001-2002) new precision measurements of J/psi- and psi'-meson masses was be performed using the resonant depolarization method for the beam energy calibration. I was working on the fields of hardware (CsI endcap calorimeter 1995-1999 and LKr barrel calorimeter 1999-2003), software (Data Base for calibrations from 2000) and physics (ee->ee scattering for luminosity needs and J/\psi->ee 2001).

I deal with simulation of processes, which take place in High Energy Cosmic Rays. The title of my diploma is "Simulating energy response of the ATIC calorimeter". The goal of the ATIC (Advanced Thin Ionization Calorimeter) experiment is to understand mechanisms and sources of Ultra High Energy Cosmic Rays. This device was launched round the South Pole during 20 days. I am going to work on data analysis we obtained in the experiment and study of Cosmic Rays acceleration mechanisms.

In the first year of my Ph.D. I was involved in the development of a new trigger at the H1 experiment at HERA. This new Fast Track Trigger (FTT) will be able to trigger on track topologies within 20us. I was working on the online/readout software of this device. At present I have just started an analysis on H1 data which aims to search for the Higgs Boson in the 2-Higgs-Doublet model. As the LEP data cannot completely rule out a light higgs boson within this model, the hope is to get a better exclusion limit with the HERA (gluon-gluon-fusion) processes.

My Ph.D. thesis uses the data collected at Dzero, one of the two experiments of the Tevatron (Fermilab) which is a hadron collider at 1.96 TeV. My thesis subject is a study of Standard Model Higgs in the channel WH going to lepton-neutrino and bbbar. In order to look for this signal, the first step of my analysis is the measurement of the cross section W+jets. This is done to reduce the background of Wbbbar events. From the hardware side, I am contributing to the calibration of the calorimeter which requires an extensive analysis of calibration data.

Since my diploma thesis I am a member of the H1 collaboration. The aim of the H1 experiment is to study ep interactions at the electron proton storage ring HERA located at DESY in Hamburg. My thesis was concerned with the development of algorithms to identify J/Psi mesons with the help of the Fast Track Trigger. This trigger system is presently being completed to cope with the increased luminosity after the HERA upgrade. Currently I am working on my Ph. D. thesis dealing with the measurement of the proton structure function F_2. This inclusive analysis aims for the extraction of parton density functions and the strong coupling constant with high precision.

After completing my Diploma Thesis at NA48, the CP-Violation measurement at CERN, where I was performing a measurement of the form factors of the K -> Pi Mu Nu decay, I am currently working for the LHCb and D-ZERO experiment. For LHCb I am involved in the development of the final design for the Silicon Tracker Trigger Station (TT). I am in charge of a Laser Test Stand where different sensor types are tested. Depending on the results a final decision will be made, on which sensors will go to our next test beam. Furthermore, I am working on an analysis at D-ZERO where I just started to look at the rare B_s -> mu mu decay. This decay has a standard model Branching ratio of 3.2*10E-9, but it might be enhanced by various SUSY models.

For my Ph.D thesis I worked with the ATLAS experiment, one of the four LHC collider experiments. I performed studies for the Alignment of ATLAS Muon Chambers for Calibration with Cosmic Rays in the Cosmic Ray Test Facility located at my institute in Garching/Ludwig-Maximilians-Universtitaet. The Muon chambers which are tested here will be placed in the outer barrel of the detector. Currently I am working with the D0 experiment, one of the two experiments at the Tevatron p+p- collider at Fermilab. I performed studies for the D0 reconstruction software and developed this code especially for the reconstruction of Muons. Currently I am working on the analysis for a supersymmetry search in the Trilepton channel of the mSUGRA model, with Muons in the final state. This channel is the so-called "golden channel " having the cleanest signature for a Supersymmetry signal. This analysis includes a careful study of the simulated Monte Carlo backgrounds and a good knowledge of the Muon reconstruction efficiencies and triggers used for my analysis.

For my Ph.D. Thesis I am trying to measure the CKM matrix element |Vub| at the BELLE spectrometer on KEK-B e+e- collider in Japan. The collider is tuned on the Y(4S) resonance and is producing B mesons in a low background environment, suitable for precision measurements of rare B decays. For my analysis I reconstruct one of the B mesons produced in pair and on the other preform an inclusive measurement of the branching fraction of semileptonic charmless decays. I am involved in both building a fully reconstructed sample and measuring the branching fraction. I also participate in the feasibility studies for particle identification upgrade of the BELLE detector with Proximity Focused Ring Imaging Cherenkov Counter.

I am currently doing my Ph.D. at ZEUS / HERA / DESY in Hamburg. The common task of my Ph.D. thesis was the simulation of synchrotron radiation background in the ZEUS detector at the upgraded ep-collider HERA. The currently ongoing redesign of the ZEUS interaction region is based on the results obtained. The physics topic of my thesis are studies of bbar correlations in beauty production at HERA. It is intended to use the new ZEUS silicon vertex detector by tagging secondary vertices produced by decaying B mesons. I have started the analysis with studies of semileptonic b-decays in ZEUS.
