I am working in the Charm Photoproduction experiment FOCUS at Fermilab. I started my collaboration with FOCUS during my degree in Physics and I am now continuing my activity for Ph.D. In particular, I am working on the Dalitz plot analysis of Charm Meson decays. Dalitz plot analysis provides unique information about the dynamics of the decay and the role of final state interactions. The very high statistics available in FOCUS allows for investigations of rare and suppressed decays. I am studying the double and he single Cabibbo suppressed channels D+ -> K+ pi- pi+ ( ~ 200 events) and Ds+ -> K+ pi- pi+ (~ 600 events). The measurements of decay fractions and relative phases, extracted from the amplitude analysis of these rare modes, are important to complete the Charm experimental scenario.

For my Ph.D. thesis I am working on AMS-02, a cosmic ray experiment which will be installed on the International Space Station in 2005. AMS-02 has been thought to measure the Antimatter abundance and study the Dark Matter nature. During the last two years, I have developed a Monte Carlo study of the AMS rejection power between protons and positrons; this feature will be essential to recognise the Neutralino annichilation products. Recently I have performed analysis of the data collected in two different Test Beam, studying the performance of the electromagnetic calorimeter of AMS. Now I am working on a possible implementation of an calorimeter stand alone trigger for gamma.

I am a Glasgow PhD student on the CDF experiment at Fermilab. During my first year as a PhD student I helped to test, install and cable the Silicon Vertex detector and was involved in its commissioning at the commencement of CDF Run II. This required working in a team of experts identifying and solving problems in the silicon detector. I developed monitoring techniques and test code to identify troublesome components and to validate the silicon detector data taking; this is an ongoing committment. In run II, CDF has included a new trigger designed to identify B semileptonic decays through the presence of a lepton incoincidence with a displaced vertex. I have been analysing this sample: in particular reconstructing D mesons and lepton tracks so as to test the trigger's efficacy. Ihave cleanly identified the D0 (-> K-pi+) and have isolated the D+ (-> K-pi+pi+) in data. Adapting these methods to the reconstruction of a lepton and D+_s meson ( -> K-K+pi-) should lead me to a measurement of the B0_s lifetime via the spatial distribution of the displaced vertices.

For my D.Phil Thesis I am working on ZEUS, one of the two hadron-electron colliding beam experiments located on HERA at DESY. To this end I have worked extensively on the hardware for an optical alignment system for the new ZEUS microvertex detector for the current HERA/ZEUS upgrade.At the same time I am part of a small expert team for the CTD, the key tracking component of ZEUS, performing regular maintenance on it. In Physics I am working on a measurement of the cross section for single W production at HERA using the decay hadronic channel.

For my PhD thesis i am working on the problem of anomalous soft photon production in hadronic collisions. My work involves data analysis from a special setup of the WA102 experiment(pp in 450 GeV/c)dedicated to study this problem, and simulation of the experiment. Specifically, i am interested in the detection of gammas produced in the collisions via their materialisation on a Pb sheet, and furthermore the comparison with those produced by the detailed simulation of this process through EGS(Electron Gamma Shower). In addition, i am interested in heavy ion physics, our team joined the NA57 experiment last year,and last summer i took part in the data taking.

Iím in the second year of my D.Phil working on developments for the alignment of the ATLAS semiconductor tracker (SCT). An alignment grid of laser interferometers has been proposed to measure distortions of the SCT on short time scales. This system is based on Frequency Scanning Interferometry (FSI), and will complement track and initial X-ray survey data, in the final alignment strategy. Iím currently involved in testing alignment grids with the prototype FSI system, and comparing their performance with simulation. For my analysis I hope to examine how the alignment tolerances seen at current experiments might be used to predict the effects of misalignment at ATLAS.

I'm working in ZEUS, one of the four experiments at the HERA e-p collider at DESY. For my diploma thesis I performed study of properties of the aerogel detector for the luminosity measurement at ZEUS. For my PhD thesis I'm working on the analysis of Deeply Virtual Compton Scattering. My goals are to determine differential cross sections for the DVCS process in the kinematic region accessible at HERA and positron-electron asymmetry . Moreover I work in the group responsible for measuring the luminosity for ZEUS. Also I'm engaged with the software development for ZEUS analysis.
