D. RESEARCH ACTIVITIES.

I'm currently involved in the following activities for the ATLAS Detector:

1. WW scattering as a way to probe dynamic breaking of the Electroweak Symmetry. See Publication/Conference [1].

2. Level 2 Trigger. See Publication [2].

During my studies for the MSc Degree, I worked on:

1. Physics studies and discovery potential of the Higgs particle through the channel , at the ATLAS detector. I studied probable misalignments of the muon drift chambers and how these could affect the reconstructed Higgs mass. For this, I developed a C++ code , which fits the muons' momenta under the constraint of the invariant mass of the Z boson, using the Langrange multipliers.

2. Software development for the data aquisition during the construction of the drift tubes for the ATLAS detector. The software contributes to the assembly line by providing, on the one hand, a way for presision measurments and controls of the temperature, the wire's mechanical tension and the tube's length, on the other hand, an automatic recording of the data and finally filling up the global database.

3. Support of the local database for the drift tubes' assembly line at the University of Athens. The task includes the update of the local database and the constant support of the team's web-page.

• August 2001, European Center for Nuclear Research (CERN) : Installation and calibration of the hodoscope for the BIS test chamber, at X5/GIF beam area. 24 scintillators and photomultipliers were installed and arranged into two layers. The hodoscope is going to provide the trigger signal for the data acquition from the BIS drift chamber. I studied the timing resolution of the whole system using the timing spectra from cosmic muons. The calibration constants for each pair of overlapping scintillators were finally derived.

E. ACADEMIC TEACHING EXPERIENCE.

Supervision of the following laboratories:

• September 2005 - December 2006 : Phys1B40 (Computing),
  Department of Physics, University College London.

• September 2001 - May 2003 : Physics III (Electromagnetism), Nuclear Physics, Advanced Nuclear Physics.
  Department of Physics, University of Athens.

Occasionally, I delivered private courses to the students, covering modules in Quantum Mechanics, Nuclear Physics, Maths, Probabilities and Statistics.

F. COMPUTING/TECHNICAL SKILLS.

1. Windows, Unix (Linux) operating systems.

2. C/C++, Fortan, Visual Basic, ROOT, Pascal, LabView programming languages.

3. Access and MySQL databases.

4. WEB design in HTML, PHP.

5. Familiar with many typesetting (eg. L^ATEX) and graphics tools and with most of Microsoft's packages.

6. CAMAC, VME platforms for data aquisition in High Energy Physics.

G. FOREIGN LANGUAGES.

English, French

H. DISTINCTIONS.

1. 'Alexander S. Onassis' Foundation.

2. University College London.

3. Particle Physics and Astronomy Research Council.
