For my Ph.D. thesis I am working on OPERA, a detector that will be installed in Gran Sasso Laboratory along CNGS neutrino beam. I have performed study on electromagnetic shower in OPERA brick for electron identification and energy measurement, that are crucial for the study of tau->e channel in vu_mu->vu_tau oscillation and for v_nu->vu_e oscillation. Now I am working on a Monte Carlo simulation of the emulsion for exploiting the experiment performances. This includes preparation of test beams and successively data collection from emulsion by using automatic microscope system and finally data analysis.

As part of my PhD I am working on the BaBar experiment at SLAC which was designed to study B-Mesons produced at the Y(4s) resonance in e+e- collisions by the PEP-II storage ring. My special interest is in semileptonic B-decays B->Xlv and the measurement of the moments of the M_x distribution, where M_x is the invariant mass of the X-system. The aim of this analysis is to use these moments in order to determine V_cb, one of the entries in the CKM-matrix. The measurement is carried out on an event sample where one B meson is fully reconstructed, thereby fully exploiting the available kinematic information. In addition I am involved in the calibration of the crystals of the BaBar Electromagnetic Calorimeter. Here I am developing and implementing an energy calibration for photons from 1-8 GeV using Virtual-Compton-Scattering events.

For my Ph.D thesis I am working on the quality assurance of detector module production in the Semi-Conductor Tracker barrel of ATLAS, one of the detectors for the LHC at CERN.
Currently I am writing software for the detector read out system, the ROD. This will be used in the testing of modules once they are assembled on to a barrel or endcap disc.
I am starting a physics analysis in the area of multiple vector boson production in ATLAS.

For my PhD thesis I'm working on ATLAS, an experiment which will operate at the futur Large Hadron Collider at CERN. The First part of my work deals with the analysis of the test beam data taken for 4 modules of the electromagnetic barrel modules. I've studied the uniformity and the resolution of the detector, and I've looked more espatialy to the effects due to the geometry of the calorimeter on the response of the detector to a 245 GeV electron beam. The second part of my work consists in studying the capability of the ATLAS detector to discover new neutral gauge bosons which appear in GUT theories.

I'm a PhD student member of the ZEUS collaboration. For my diploma thesis I've searched for lepton flavour violating processes (e p->mu X) at HERA. Such interactions could be mediated by leptoquarks or squarks in R-parity violating supersymmetric models. In my first year of PhD I've performed an analysis on multi-muon production at HERA. Now I'm extending the lepton flavour violation analysis at the process e p ->tau X. I'm also working on the development of the software for the ZEUS event display (ZeVis) based on ROOT libraries. Since 2002 I'm coordinating the Data Quality Monitor for the exotic group.

For my Ph.D. thesis I'm working in Cosmic Ray Division of YerPhI. We are conintuosly registering secondary particles (electrons, neutrons, muons and along with directional information of muons) from cosmic rays with energy up to several ten GeV. These particles highly affected by Solar disturbances (so called Coronal Mass Ejecta and Solar Flares). These events could be dangerous enough to destroy a big chunk of satellite fleet or result in deadly radiation doze for people in space. I'm working on developing methods and software for both real-time and off-line analysis of data observed from our detectors. In furtue on this basis an alert service should be made which could smooth the consequences of these events.

I am in the second year of my Ph.D. studies, working on physics simulation for the ATLAS experiment currently under construction at CERN.
The first project I am involved in is trying to extend the expected discovery region for the charged Higgs boson within the MSSM parameter space (M_A,tan(beta)) at high charged Higgs masses (>~400 GeV). This study is based on ATLAS fast simulation ATLFAST.
Recently I started to study the tau identification performance of the ATLAS detector utilizing the ATLAS full detector simulation (Geant3). This analysis is computationally expensive and is performed on the nordic grid testbed, Nordugrid. The results of this study will be used to study charged Higgs decaying to tau nu_tau.

I'm currently working for my Ph.D. on the D0 experiment which takes palce in Fermilab. My main topic is focused on the Top quark study in the single-top mode (cross-section measurement). Also an attempt to measure the Vtb coupling value can be done to a precision level reaching ~15%.
The first approach is done by the mean of a b-tagger tool on which I am working since one year. Also I am contributing in the developpement of the official experiment's code and worked on the data analysis level to help in monitoring the silicon tracker.
