Current position: GDF SUEZ Tractebel Engineering.
I am involved in the following research directions:

Device simulation of semiconductors sensors

Development of simulation tools at device level for semiconductor sensors. We are interested both in the simulation of static characteristics as for instance coupling capacitances, electric fields, etc, but also dynamic characteristics as signal developed in different sensors when particles are passing through.

Tools used to made this simulations are based in comercial software as TCAD or Silvaco and programs developed by ourselves. This work profits from the close collaboration with DICE (FSA/UCL).

External collaborators: Denis Flandre (UCLouvain - EPL).

Neutron irradiations with UCL cyclotron

Metrology and instrumentation of CYCLONE-110 T2 irradiation line to test semiconductor sensors and electronics under neutron fluences (max Formula: 0 neq/cm2).

External collaborators: Michael Moll (CERN).

The CMS silicon strip tracker upgrade

Development of the "phase II" upgrade for the CMS silicon strip stracker.

More precisely, we are involved in the development of the uTCA-based DAQ system and in the test/validation of the first prototype modules. We take active part to the various test-beam campaigns (CERN, DESY, ...)

This activity will potentially make use of the cyclotron of UCL, the probe stations and the SYCOC setup (SYstem de mesure de COllection de Charge) to test the response to laser light, radioactive sources and beams.

The final goal is to take a leading role in the construction of part of the CMS Phase-II tracker.

External collaborators: CRC and CMS collaboration.

I am involved in the following research directions:

CMS Tracker commissioning at the Magnet Test Cosmic Challenge

The so called Magnet Test Cosmic Challenge (MTCC) was the first comprehensive operational and functional test of the CMS experiment. the MTCC took place in the first months of 2006 and was a slice test in which a small fraction of all the CMS detection equipment was operated in the 4 T solenoid of the experiment. Cosmic rays detected in the muon chambers were used to trigger the readout of all detectors in the global CMS data acquisition system. Prior to data taking, the detectors and their readout electronics were tuned and synchronized with dedicated software procedures. Local reconstruction was carried out online and offline in all sub-detectors for event selection and monitoring purposes. Global reconstruction, linking different sub-detectors, was performed mainly offline. A number of monitoring and visualization tools were also used for validation purposes and monitoring. One of the main goals of the MTCC was the validation of the hardware alignment system functionality.
At the MTCC, UCL had a leading role in the preparation, operation and offline data analysis related to the silicon strip tracker detector.


Cryogenic detectors development for very high radiation environment.

External collaborators: RD39 collaboration.

Silicon strip detectors telescope

Construction of an multiple-plane of silicon strips modules (detectors and readout) as an instrument for particles tracks reconstruction and prototype modules testing.


SYCOC stands for "SYstem de mesure de COllection de Charge". This system is intended to measure charge collection efficiency of semiconductor detectors with both a laser and radiactive sources. This installation is used in the characterization of semiconductor detectors in order to study its radiation hardness. This project is done in collaboration with RD50 team at CERN.

External collaborators: Michael Moll (CERN).
