2012 – today: Member of the CaLIPSO team: development of innovative detectors for PET imaging.

The CaLIPSO project is a development of the innovative PET detectors for the brain and pre-clinical studies. This is an efficient, fast detector with high spatial resolution. It uses the heavy TMBi liquid as a detection media. This media provides two types of signal: the fast optical signal due to the Cherenkov light and a signal from the ionization used for the precise spatial localization.

The PECHE project is a development of the efficient and extremely fast TOF-PET detectors based on the “scintronic” crystal, producing both Cherenkov light and scintillation and integrated with the photodetection layer and photo-multiplication device.

2003 – 2016: study of the top quark with the D0 detector

Member of the D0 international collaboration. D0 experiment studies the pp collisions at the center-of-mass energy 1.96 GeV at the Tevatron collider, Fermilab USA. The main contributions to the experiment are: operation of the D0 calorimeter; noise studies and developing of the noise suppression system in the D0 calorimeter; developing of the on-line controls for the calorimeter; muon  identification; calibration of the reconstructed quark jets; developing of the system for the calibration and selection of the detector output data; coordination of the analysis data processing; studies of the top quark; coordination of the top quark activities in the D0 collaboration.

1999 - 2004: Study of the crystal source of the positrons.
